Adding IP Addresses to Your Server

Introduction

While every server comes with a primary Public IP address, your infrastructure may require additional IPs to support specific configurations. Whether you need to isolate email reputation, manage custom Reverse DNS (rDNS) records, or segment traffic for security, you can easily expand your network allocation.

Depending on your server type, you can add up to 7 IPs (VPS) or 3 IPs (Dedicated) directly via the portal.

IP Address Justification Guidelines

Due to the global scarcity of IPv4 addresses, all requests for additional IPs must adhere to ARIN regulations. When requesting an additional IP, you must provide a valid technical justification.

Need More IPs? Consider IPv6

If your application requires a large number of unique addresses, consider utilizing IPv6. Unlike the strictly limited IPv4 standard, IPv6 addresses are abundant and do not require the same level of technical justification.

Valid Justifications

SSL Certificates: You may require a dedicated IP to install an SSL certificate for legacy browser compatibility or specific security configurations.
Application Requirements: Certain applications (such as custom chat servers, listeners, or gaming servers) that strictly require a unique IP address to function are valid justifications.
Nameserver Requirements: Specific Top-Level Domain (TLD) registries (such as .ru) require nameservers to reside on separate subnets (different /24s). This is the only valid justification for requesting IPs on a specific, separate subnet.
Multiple Domains: Hosting multiple distinct domains is a valid justification. However, you must provide a list of the domains you intend to host so our team can verify the request.

Invalid Justifications & Limitations

Search Engine Optimization (SEO): Dedicated IPs do not influence search rankings. Google has confirmed that using a shared IP does not negatively impact SEO. For more information, please see Google’s Webmaster Guidelines.
Email Deliverability: improving email reputation or deliverability is not considered a valid technical justification for a dedicated IP address.
Class C / Subnet Selections: We cannot fulfill requests for IPs on specific different subnets (e.g., requesting one IP on 69.227.15.x and another on 69.227.16.x) for SEO or general hosting purposes. The only exception to this rule is the TLD nameserver requirement mentioned above.

Bulk IP Requests for High-Volume Applications

If you run applications that require unique IPs for multiple instances (such as game servers or reseller environments), you may be eligible to request IP blocks in advance. To qualify, you must provide verification, such as screenshots or configuration logs, demonstrating that your current IP allocation is fully utilized. All bulk requests are reviewed on a case-by-case basis by our Networking team. Contact our sales team for more information.

Prerequisites

Administrative access to your Liquid Web account.
A Cloud VPS or Dedicated server.
A valid technical justification for your request.

Step-by-Step Instructions

Log into your portal.liquidweb.com account with yourusername and password, orsign in with Google SSO.
Click the Servers tab on the left-hand navigation menu and select My Servers.
Click on the name of the server you wish to modify.
Click on the Networking tab.
Locate the IP Addresses section. This block displays your currently assigned IPs and the number of “slots” remaining for new addresses. Click the Add another button.

The next steps depend on your specific server type:

For Cloud VPS Servers

Our automated systems can quickly add or remove IPs from a Cloud VPS.

Linux Servers: A reboot is required to activate the new IP.
Windows Servers: A reboot is generally not required.

By default, you can add new IPs. Alternatively, if you have reserved IPs, you can assign an IP from your IP Pool.
Choose the number of IPs to add, or select from your pool.
A reboot is required to activate the new IP.
- To reboot immediately, ensure Reboot now and add automatically is toggled ON.
- To delay the reboot, toggle this option OFF. The IP will be reserved but will not function until you manually reboot the server.
Click Confirm.
You can track the progress of the addition in the Notifications section of your account.

For Dedicated Servers

Requests for Dedicated servers require manual review by our Networking team.

Select the Number of IPs you wish to add.
Enter your Justification and business needs for the additional addresses (refer to the guidelines above).
Click the Request button.
This action creates a support case with our Networking department. Please follow along in the case for updates.

Downtime Required (Linux Only)

Adding IPs to a dedicated Linux server requires a network reconfiguration and a reboot. The support team will coordinate this downtime with you. Windows servers generally do not require a reboot.

Next Steps

Configure the IP: Once the IP is added to the server, you may need to configure your control panel to recognize it. See Adding IP Addresses Manually in WHM.
Cleanup: To learn how to remove unused addresses, see Deleting IP Addresses from Your Cloud VPS.

Frequently Asked Questions (FAQ)

It depends on your operating system.

Linux Servers: Yes. Adding a new network interface requires the server to reboot to update its configuration.
- For Cloud VPS: You can choose to reboot immediately or delay it, but the new IP will not function until the server is restarted.
- For Dedicated Servers: Support will coordinate a maintenance window with you to perform the necessary network restart.
Windows Servers: No. In most cases, Windows servers can add IPs without a reboot.

No. Google has explicitly stated that sharing an IP address with other sites does not negatively affect search rankings. Requests for IPs solely for SEO purposes will be denied.

No. We cannot fulfill requests for IPs on specific subnets (e.g., requesting one IP on x.x.15.x and another on x.x.16.x) unless it is a registry requirement for nameservers (such as for .ru domains).

The most common reasons for denial are:

Insufficient Justification: Listing “SEO” or “Email Deliverability” as the reason.
Underutilization: You have not used the IP addresses already assigned to you.
Format: You did not provide the specific list of domains that require the new IPs.

Yes! If your application supports it, IPv6 is a great alternative. IPv6 addresses are abundant and do not require the strict technical justification process that IPv4 addresses do.
