DigitalBerg Virtual Private Servers for WordPress: A Complete Guide to Faster, More Reliable WordPress Hosting

1 Comment

WordPress has become one of the most widely used platforms for building business websites, blogs, online stores, portfolios, membership websites, and content-driven platforms. But as a WordPress website grows, traditional shared hosting may no longer provide the performance, flexibility, and control that the website requires.

This is where a Virtual Private Server for WordPress can make a significant difference.

A WordPress VPS provides an isolated hosting environment with dedicated resources and greater control over the server configuration. It can be a practical option for businesses, developers, agencies, and website owners who have outgrown shared hosting but do not necessarily need a dedicated physical server.

DigitalBerg Virtual Private Servers for WordPress are designed for users who want more control, performance, flexibility, and reliable infrastructure for their WordPress websites.

What Is a VPS for WordPress?

A Virtual Private Server is a virtualized server environment that runs on physical server infrastructure. Unlike traditional shared hosting, where many websites share the same hosting environment and compete for resources, a VPS provides an isolated environment with resources allocated to your virtual server.

For WordPress users, this can provide greater control over:

Server resources
Operating system
Software configuration
WordPress environment
Security settings
Server-level optimization
Applications and services
Website scaling

DigitalBerg’s VPS infrastructure is built around high-performance virtual servers, SSD storage, root access, and flexible server configurations.

Why Does WordPress Need Better Hosting as It Grows?

A new WordPress website may work perfectly well on basic shared hosting.

However, as traffic, content, plugins, customers, and functionality increase, hosting requirements can change.

For example, a growing website may experience:

Slower page loading
Higher resource usage
Increased database activity
More simultaneous visitors
Plugin and application demands
Traffic spikes
Limited server configuration options

Shared hosting can be suitable for smaller websites, but websites with increasing resource requirements may benefit from moving to a VPS.

A VPS gives the website owner more control over the hosting environment and allows server resources to be managed according to the website’s requirements.

Benefits of Using a VPS for WordPress

1. Dedicated Resources for Better Consistency

One of the major advantages of VPS hosting is resource isolation.

Instead of relying entirely on a shared hosting environment, your WordPress website operates inside its own virtual server environment.

This can help provide more predictable performance when compared with heavily shared environments.

DigitalBerg describes its VPS infrastructure as providing dedicated resources and isolated VPS environments.

For WordPress websites receiving regular traffic, this additional resource control can be particularly useful.

2. SSD Storage for Faster Website Operations

Storage performance matters for WordPress because websites constantly read and write data.

Your WordPress installation, database, themes, plugins, media files, and other website resources all depend on server storage.

DigitalBerg offers SSD-powered VPS infrastructure designed for high performance workloads. Its VPS information highlights SSD storage and high I/O performance as part of the platform.

Faster storage can contribute to improved server responsiveness, although overall WordPress speed also depends on factors such as:

Website code
Theme quality
Plugins
Database optimization
Caching
Images
CDN configuration
Network performance

In other words, VPS hosting is an important part of the performance equation, but it is not the only factor.

3. Full Root Access

Another important advantage of VPS hosting is control.

DigitalBerg VPS solutions provide root access, giving technically experienced users greater control over their server environment.

With root access, users can configure their environment according to their technical requirements, install appropriate software, manage services, and make server-level changes.

This is particularly useful for:

WordPress developers
Agencies
System administrators
Advanced website owners
Businesses with custom requirements

If you are not comfortable managing a server, however, it is important to understand what level of management and support you require before selecting a VPS.

4. More Control Than Shared Hosting

Shared hosting is designed to simplify website hosting. It can be a good starting point, but it generally provides less control.

A VPS sits between shared hosting and a dedicated server in terms of infrastructure and control.

You receive your own virtual environment while using physical server infrastructure that may host multiple virtual machines.

This makes VPS hosting an attractive option for websites that need more flexibility without immediately moving to a dedicated server.

DigitalBerg VPS for WordPress: Why Consider It?

DigitalBerg has a long-standing focus on hosting, VPS infrastructure, cloud solutions, and WordPress. The company specifically highlights WordPress expertise as part of its services and says WordPress installation is one of its core areas.

DigitalBerg’s hosting infrastructure also emphasizes SSD performance, scalable hosting, dedicated support, and server-level control.

For WordPress users, this combination can be useful when moving beyond basic shared hosting.

Key DigitalBerg VPS Features

Depending on the VPS configuration, DigitalBerg provides features such as:

SSD-based storage

DigitalBerg’s published VPS information also lists options for control panels such as Plesk and cPanel, along with support and VPS management features.

Is a VPS Better Than Shared Hosting for WordPress?

There is no single hosting solution that is best for every WordPress website.

The right choice depends on your website’s traffic, technical requirements, budget, expected growth, and level of server management experience.

Feature	Shared Hosting	WordPress VPS
Resource isolation	Limited	Higher
Server control	Limited	High
Root access	Usually unavailable	Available with VPS
Scalability	Limited	More flexible
Custom configuration	Limited	Extensive
Suitable for growing websites	Sometimes	Often
Technical knowledge	Lower	Higher
Performance control	Limited	Greater

If you are running a small personal blog with limited traffic, shared hosting may be sufficient.

If you are managing a business website, eCommerce store, high-traffic blog, membership platform, or multiple WordPress installations, a VPS may provide the additional flexibility you need.

When Should You Move WordPress to a VPS?

There is no fixed traffic number that automatically means you need a VPS.

Instead, look at the symptoms and requirements of your website.

You may want to consider VPS hosting if:

Your Website Is Consistently Slow

If your WordPress website remains slow despite optimizing images, plugins, themes, caching, and other website elements, the hosting environment may need to be reviewed.

You Are Experiencing Resource Limits

Frequent CPU, RAM, process, or other hosting resource limitations can be a sign that your website has outgrown its current hosting plan.

Your Traffic Is Increasing

A growing audience means more simultaneous requests and server activity.

A VPS can give you more control over available resources as your website grows.

You Need Server-Level Customization

Developers and agencies often need to install specific software or configure server services.

A VPS provides considerably more control than typical shared hosting.

You Are Hosting Multiple WordPress Websites

Agencies, developers, and businesses managing several websites may benefit from a VPS environment that provides more control over hosting resources and server configuration.

VPS Hosting for WordPress Developers and Agencies

Developers often need more flexibility than standard hosting plans provide.

A VPS can provide a development-friendly environment where professionals can configure server settings, install required software, manage applications, and control their hosting environment.

For agencies, VPS hosting can also be useful for hosting multiple client websites.

Instead of purchasing separate basic hosting accounts for every project, an appropriately configured VPS can provide a centralized environment.

However, resource planning is important. The VPS should have enough CPU, RAM, storage, and network capacity for the number and type of websites being hosted.

VPS Hosting for WooCommerce Websites

WooCommerce adds additional complexity to a WordPress website.

An online store may need to handle:

Product searches
Customer accounts
Shopping carts
Checkout processes
Payment integrations
Inventory operations
Database queries
Order processing

During promotional campaigns or seasonal sales, traffic can also increase quickly.

For growing WooCommerce stores, having greater control over server resources can be valuable.

A VPS can provide a stronger infrastructure foundation, while WordPress and WooCommerce optimization should still be handled at the application level.

How VPS Hosting Can Support WordPress Performance

Website speed depends on many components.

A well-configured VPS can provide a strong foundation, but the WordPress website itself must also be optimized.

For better performance, consider combining VPS hosting with:

Page caching
Object caching
Image optimization
Lightweight themes
Optimized plugins
Database maintenance
Content Delivery Network (CDN)
GZIP or Brotli compression
Updated PHP version
Optimized server configuration

This approach is more effective than expecting hosting alone to solve every performance problem.

WordPress Security on a VPS

Hosting security should be treated as a combination of infrastructure and website-level protection.

At the server level, VPS users can implement appropriate security measures such as:

Strong authentication
Secure SSH configuration
Firewall rules
Regular software updates
Malware monitoring
Security plugins
Least-privilege access
Regular backups
Monitoring and logging

WordPress itself should also be kept updated.

Themes and plugins should be maintained carefully because outdated software can introduce security risks.

DigitalBerg also publishes an Acceptable Use Policy covering its VPS, cloud infrastructure, and related hosting services.

Backup and Recovery Considerations

No hosting environment should be treated as a substitute for a proper backup strategy.

Before moving a WordPress website to a VPS, consider:

How frequently backups are created
Where backups are stored
How long backups are retained
Whether backups are separate from the main server
How quickly the website can be restored
Whether database backups are included

DigitalBerg’s VPS information includes snapshot functionality and optional backup-related features on certain configurations.

For important business websites, maintaining an independent backup strategy is still recommended.

How to Choose the Right VPS for WordPress

Choosing the right VPS configuration is not simply about selecting the largest available server.

Start with your actual requirements.

Consider Your CPU Requirements

Websites with dynamic functionality, WooCommerce, complex plugins, or high traffic may require more processing power.

Consider RAM

RAM affects how many processes and applications can operate efficiently.

A basic blog and a large WooCommerce store will not necessarily have the same memory requirements.

Consider Storage

Estimate your current website size and future requirements.

Remember to consider:

WordPress files
Images
Videos
Databases
Backups
Logs
Additional applications

Consider Network Capacity

If your website receives substantial traffic or serves large files, network capacity becomes increasingly important.

DigitalBerg’s VPS infrastructure includes high-speed network connectivity and options designed for demanding workloads.

Consider Management Requirements

A technically experienced developer may prefer full control.

A business owner who does not work with server administration may require more support or management.

Always consider your technical capabilities before selecting a VPS.

DigitalBerg VPS vs Dedicated Server for WordPress

A VPS and dedicated server serve different needs.

A VPS provides a virtualized environment and is generally a more accessible step up from shared hosting.

A dedicated server gives you an entire physical server and therefore provides greater control over physical resources.

DigitalBerg offers both VPS and dedicated server solutions, allowing customers to select infrastructure based on their requirements.

Choose a VPS If:

You need more control than shared hosting
Your website is growing
You need dedicated virtual resources
You want flexible server configuration
You do not yet require an entire physical server

Consider a Dedicated Server If:

You have consistently high resource requirements
You need maximum physical resource control
You are running demanding applications
You require specialized server configurations

The best solution depends on your workload rather than simply choosing the most powerful option.

Common WordPress VPS Mistakes to Avoid

Moving to a VPS can provide more control, but it also creates additional responsibilities.

Choosing Too Much or Too Little RAM

More resources are not always necessary. At the same time, an underpowered server can create performance issues.

Review your current resource usage before choosing a plan.

Installing Too Many Plugins

A powerful server cannot compensate for poorly optimized WordPress plugins.

Remove unnecessary plugins and regularly review your WordPress installation.

Ignoring Updates

Keep WordPress, themes, plugins, operating systems, and server software updated according to your maintenance strategy.

Not Creating Backups

A VPS is not automatically a complete backup solution.

Make sure your backup and recovery strategy is clearly defined.

Forgetting Server Security

Root access provides control, but it also means configuration and security responsibilities must be handled properly.

Understanding Virtual Private Servers

Virtual private servers (VPS) are a great step up for those outgrowing basic hosting plans. They offer more control, power, and flexibility, allowing your website to perform better under heavier loads.

VPS vs Shared Hosting

Shared hosting is where multiple websites share a single server. It’s like sharing an apartment with roommates—you split resources, which can lead to conflicts. If one site hogs bandwidth, everyone else suffers. The cost is low, making it a popular start for beginners. But when traffic spikes, performance can drop drastically. In contrast, a VPS gives you your own space. Think of it as having your own condo. You have dedicated resources, which translates into more stability and better performance. You won’t compete with others for bandwidth, ensuring your site runs smoothly even during high traffic.

For many small businesses and growing blogs, VPS hosting is the logical next step. Learn more about the benefits of VPS hosting.

VPS vs Dedicated Hosting

Dedicated hosting is like owning a house—you have full control and access to all server resources. It’s powerful but comes with a hefty price tag. A VPS, on the other hand, offers a middle ground. You get many benefits of a dedicated server without the full cost. With a VPS, you enjoy customisation and root access, allowing you to install preferred software and configure settings to your liking. While dedicated servers provide maximum power, they can be overkill for many sites. VPS hosting is ideal for those who need flexibility and control without the financial strain of dedicated hosting.

For businesses and developers, understanding these differences can guide better hosting decisions. Explore more about VPS hosting solutions.

Key Use Cases for VPS Hosting

Moving to a VPS can be a game-changer in how your business scales and adapts to demands.

Small Business Scalability

Small businesses often start with shared hosting but soon encounter limitations. As your business grows, so does your website traffic. A VPS provides scalability and dedicated resources, ensuring that your site can handle increased visitors without a hitch. You can easily upgrade your plan as your needs expand, making VPS hosting a cost-effective solution for growing companies. Many small businesses find that VPS hosting strikes the perfect balance between affordability and capability. By choosing VPS, you set your business up for long-term success. Find out how VPS can benefit your small business.

Developer-Friendly Environment

Developers need control and flexibility to test applications and deploy updates. A VPS offers a customizable environment with root access, letting you tailor the server to your needs. This freedom is crucial when developing new applications or running scripts. You can install any software and configure settings without restrictions. Plus, a VPS allows you to create multiple environments, such as staging and production, on the same server.

DDoS-protected VPS hosting 2026 infographic showing mitigation of UDP floods, SYN floods and HTTP attacks

DDoS-Protected VPS Hosting in 2026: Security, Mitigation and Buying Guide

0 Comments

DDoS-protected VPS hosting combines the flexibility of a virtual private server with network and application defences designed to keep legitimate users connected during distributed denial-of-service attacks. In 2026, a secure VPS needs more than a firewall or a high-bandwidth port. Buyers should understand the attack types a provider mitigates, where filtering occurs, how applications are protected and what happens when an attack exceeds the contracted service limits.

This guide explains DDoS protection for VPS servers, compares network-layer and application-layer mitigation, shows practical Linux hardening steps and provides a checklist for evaluating hosting providers. It is intended for websites, APIs, SaaS platforms, ecommerce applications and game servers.

What Is DDoS-Protected VPS Hosting?

A DDoS-protected VPS is a virtual server supported by systems that detect and mitigate malicious traffic intended to overwhelm a service. The VPS still runs its own operating system and applications, but upstream infrastructure may inspect, filter, rate-limit or redirect traffic before it reaches the virtual machine. Protection capabilities vary significantly between providers and plans. A service advertised as DDoS protected is not necessarily immune to every attack.

Explore DigitalBerg VPS hosting for available virtual server configurations. Confirm the exact DDoS mitigation features and service limits for any plan before purchase.

How DDoS Attacks Affect a VPS

A distributed denial-of-service attack uses multiple sources to generate traffic or requests that exhaust a network, protocol stack or application. Even a VPS with sufficient CPU and RAM can become unreachable when upstream links saturate. Conversely, relatively modest traffic may disrupt a poorly optimised application if it forces expensive database queries or authentication operations.

Volumetric attacks: UDP floods and amplification

Volumetric attacks attempt to overwhelm available bandwidth. Reflection and amplification techniques can produce substantial traffic toward a target. Effective mitigation generally requires upstream network capacity and filtering; a firewall running only inside the VPS cannot restore connectivity after the provider’s upstream link is saturated.

Protocol attacks: SYN floods and connection exhaustion

Protocol attacks target network or transport-layer behaviour. SYN floods, for example, can exhaust connection-handling resources. Defences may include SYN cookies, connection tracking controls and upstream filtering, depending on the architecture.

Application-layer attacks: HTTP floods

Layer 7 attacks imitate application requests. They may target expensive URLs, login forms, search endpoints or APIs. A web application firewall, rate limiting, bot detection and application-specific controls are often more useful here than raw bandwidth capacity.

DDoS Protection Layers: What Actually Stops an Attack?

Protection layer	Typical controls	Best suited to
Upstream network	Traffic scrubbing, routing, filtering	Large volumetric attacks
Transport/network edge	SYN protection, ACLs, connection limits	Protocol and connection floods
Reverse proxy / CDN	Caching, WAF, bot controls, rate limits	HTTP(S) services
VPS operating system	Firewall, service hardening, resource limits	Reducing local exposure
Application	Authentication, quotas, request validation	Expensive endpoints and API abuse

These layers are complementary. For example, a reverse proxy can shield an HTTP application, but it does not automatically protect a game server using a different protocol. Likewise, a Linux firewall cannot compensate for an upstream link that is already overwhelmed.

Always-On vs On-Demand DDoS Mitigation

Always-on mitigation continuously routes relevant traffic through filtering infrastructure. It can reduce detection and diversion delays, although its latency and false-positive characteristics depend on the service. On-demand mitigation activates after an attack is detected, potentially requiring a routing or traffic-diversion change. Ask providers about activation time, routing architecture, false positives, supported protocols and incident visibility.

How Much DDoS Protection Does a VPS Need?

There is no universal attack-size threshold that guarantees safety. A provider may advertise a mitigation capacity measured in Gbps or Tbps, but the relevant questions are whether that capacity is shared, where filtering takes place, which protocols are covered and what limits apply to your specific service. For packet-intensive attacks, packets per second can matter as much as bits per second. For HTTP floods, requests per second and application cost are often more useful measures.

Evaluate the workload first: public website, API, game server, database or remote desktop. Then ask whether mitigation is available for the ports and protocols you actually use. A provider’s total network capacity should not be confused with guaranteed protection allocated to one VPS.

DDoS-Protected VPS vs Standard VPS

Feature	Standard VPS	DDoS-protected VPS
Virtual CPU, RAM and storage	Yes	Yes
Basic host firewall	May be available	May be available
Upstream attack filtering	Not necessarily	Included to a defined scope
Layer 7 application protection	Separate configuration may be needed	May still require a separate WAF
Guaranteed immunity	No	No
Incident support	Depends on plan	Depends on plan and SLA

DDoS protection should be evaluated as a specific service capability, not simply a label attached to a VPS plan.

How to Secure an Ubuntu VPS Against Common Attacks

The following steps improve general VPS resilience but do not replace upstream DDoS mitigation. Before changing firewall rules, ensure you have console access and allow the management ports your environment requires.

1. Update installed packages

sudo apt update
sudo apt upgrade

2. Configure a host firewall

For an Ubuntu web server, first permit SSH access using the actual management port and source restrictions appropriate to your setup. The following is a basic example for SSH on port 22, HTTP and HTTPS:

sudo ufw allow 22/tcp
sudo ufw allow 80/tcp
sudo ufw allow 443/tcp
sudo ufw enable
sudo ufw status verbose

Restrict SSH to known administrator IP addresses where practical. Avoid enabling a firewall before verifying that remote administration will remain accessible. See the Ubuntu firewall documentation.

3. Enable sensible web request limits

For NGINX, a request-rate zone can reduce repeated requests to selected endpoints. This is an example, not a universal production configuration:

# In the http context:
limit_req_zone $binary_remote_addr zone=perip:10m rate=10r/s;

# Inside an appropriate server/location block:
location /login/ {
    limit_req zone=perip burst=20 nodelay;
    proxy_pass http://127.0.0.1:8000;
}

Test rate limits carefully: shared NAT addresses, legitimate bursts and reverse proxies can cause false positives. If NGINX sits behind a trusted proxy, configure the real client IP correctly before applying per-IP limits. Refer to the NGINX limit_req documentation.

4. Harden SSH and administrative access

Use SSH keys, disable password authentication only after confirming key-based access works, remove unused accounts and apply least-privilege permissions. Restrict control panels, databases and internal APIs to trusted networks. Consider MFA for management interfaces where supported.

5. Monitor traffic and application health

Track interface throughput, packets per second, HTTP status codes, connection counts, CPU load and memory pressure. Alerts should distinguish a legitimate traffic spike from unusual request patterns. Keep logs with suitable retention and avoid exposing sensitive information.

Should You Use Cloudflare or Another Reverse Proxy?

A reverse proxy or CDN can help protect websites by absorbing traffic at distributed edge locations and applying WAF, caching and rate-limit rules. This is especially relevant for HTTP and HTTPS applications. It is not a complete solution for every TCP or UDP protocol. If attackers can directly reach the VPS origin IP, some protections may be bypassed; use appropriate origin-access controls and avoid unnecessarily exposing the origin address.

For architecture and mitigation concepts, see Cloudflare DDoS protection documentation and OWASP’s denial-of-service guidance.

DDoS Protection for Game Servers vs Websites

Game servers often use UDP or other non-HTTP protocols, making a standard website WAF insufficient. Prioritise protocol-aware filtering, stable routing, packet-loss performance and latency. For websites and APIs, prioritise HTTP request analysis, bot controls, rate limiting and origin shielding. For database services, do not expose the database port publicly unless strictly required; prefer private networking or authenticated tunnels.

Businesses requiring exclusive physical resources can also evaluate DigitalBerg dedicated servers, while teams seeking virtual infrastructure can review VPS hosting options.

How to Choose a DDoS-Protected VPS Provider in 2026

Check mitigation scope, not just headline capacity

Ask which attacks are covered: UDP floods, SYN floods, amplification, HTTP floods and application abuse. Confirm supported ports, protocols, maximum sustained attack conditions and whether mitigation is automatic.

Verify network performance and data-centre location

Low latency and predictable routing can be important for interactive applications. Check regional connectivity and where the VPS is physically hosted. See DigitalBerg data-centre information for infrastructure context.

Understand support and incident procedures

Clarify what the provider monitors, what customers can see in an attack report, how false positives are resolved and whether emergency support is included. A published uptime percentage does not necessarily guarantee protection against every DDoS event.

Compare full monthly costs

Evaluate vCPU, RAM, storage, backup, bandwidth, protection features, managed services and any extra mitigation charges. Avoid comparing plans solely by advertised attack capacity.

DDoS-Protected VPS Buying Checklist

Confirm the specific DDoS attack types covered.
Check whether protection applies to HTTP, TCP and UDP services.
Ask about mitigation location, detection and activation times.
Verify any attack-size, bandwidth or fair-use limitations.
Check whether origin IP protection is possible.
Review SLA exclusions, support hours and escalation procedures.
Confirm backups, snapshots and recovery options.
Evaluate latency, routing and physical server location.
Compare total costs and the scope of managed support.

Frequently Asked Questions

What is a DDoS-protected VPS?

It is a virtual private server supported by traffic filtering and mitigation designed to reduce disruption from distributed denial-of-service attacks.

Does every VPS include DDoS protection?

No. Features vary by provider and plan. Basic firewall access is not the same as upstream attack mitigation.

Can a firewall stop a large DDoS attack?

A host firewall can reduce some unwanted traffic, but it cannot restore connectivity if upstream links are saturated. Network-layer filtering must occur before that bottleneck.

Does DDoS protection stop all attacks?

No service guarantees immunity. Coverage depends on attack characteristics, mitigation architecture, capacity and service conditions.

Is a CDN enough to protect a VPS?

A CDN or reverse proxy can help protect supported web traffic. Other protocols and exposed origin IP addresses may require separate controls.

Is DDoS protection important for gaming VPS hosting?

Yes, especially when servers are publicly reachable. Protocol-aware UDP protection, latency and packet-loss performance are key considerations.

Does DDoS protection slow down a website?

It depends on routing and filtering architecture. Some protection layers add processing or routing overhead, while caching at an edge network can improve web performance.

What is the difference between Layer 3/4 and Layer 7 protection?

Layer 3/4 mitigation focuses on network and transport traffic. Layer 7 protection analyses application requests such as HTTP, often using WAF and rate-limit rules.

Final Thoughts

Choosing DDoS-protected VPS hosting in 2026 requires evaluating real mitigation capabilities, network quality, application controls and support. Effective resilience usually combines upstream filtering with careful VPS configuration and application-level safeguards. Review DigitalBerg VPS hosting and confirm the protection scope of the specific plan before ordering.

How to Configure an Additional IP Address

0 Comments

How to Configure an Additional IP Address

Applies to: AlmaLinux 8 & 9, Rocky Linux 8 & 9

For Digitalberg VPS & Dedicated Server Clients

To configure an additional IP address on your Digitalberg server, follow the steps below carefully. This guide assumes you are using NetworkManager.

Step 1: Identify Your Main Network Interface

Run the following command:

ip a

Note the name of the main network interface. This is usually something like eth0.

Step 2: Create a New Configuration File

Each additional IP requires a separate configuration file in the /etc/sysconfig/network-scripts/ directory.

Use this format for the file name:

ifcfg-NETWORK_INTERFACE:ID

For example, for the first alias on eth0, use:

ifcfg-eth0:0

Create the file using:

sudo nano /etc/sysconfig/network-scripts/ifcfg-eth0:0

Step 3: Add the Configuration

Paste the following lines into the new file, replacing the values with your actual interface and IP:

DEVICE=eth0:0
ONBOOT=yes
BOOTPROTO=none  # Use "static" for CentOS
IPADDR=ADDITIONAL_IP
NETMASK=255.255.255.255
BROADCAST=ADDITIONAL_IP

Save and close the file.

Step 4: Restart the Network Interface

Apply the changes with:

sudo systemctl restart NetworkManager

Troubleshooting

If the additional IP doesn’t respond after restarting NetworkManager, try rebooting the server.
You can also test the configuration by setting the IP manually:

ifconfig eth0:0 ADDITIONAL_IP netmask 255.255.255.255 broadcast ADDITIONAL_IP up

Then try pinging the IP from an external device.
