What do these words mean?

An IP address is the number address of a computer on the internet. It is like the street number of a house. Your server has at least one. You can add more, for example to give a site its own address or to use a separate SSL certificate.

WHM is Web Host Manager. It is the server-level panel for cPanel servers. Only the server owner, or a reseller with the right rights, can use it. This guide needs root access. Root is the main administrator account of a server. VPS and dedicated server customers have it.

Warning: Wrong network settings can cut off your server. Take a backup and keep your access method ready. Do not add an IP address that your provider has not given you.

Before you start

  • Get the new IP address from your provider. You cannot invent one. Ask Hostvento support to assign it, and check whether your plan allows more.
  • Ask for the subnet mask too. It is a number that goes with the IP address, such as 255.255.255.0.

Steps

  1. Log in to WHM as root.
  2. Type IP Functions in the search box on the left.

  4. In New IP or IP range to add, type the address.
  5. In Subnet Mask, type the mask your provider gave you.
  6. Pick the setting for Configured Interface if shown. Leave the default if you are not sure.
  7. Click Submit.
  8. Wait for the success message.

Check the new address

  1. Go to IP Functions and then Show or Delete Current IP Addresses.
  2. Look for your new address in the list.
  3. Use the same page to check which accounts use it.

Give an account the new IP

  1. Search for Change Site's IP Address in WHM.
  2. Choose the account or domain.
  3. Pick the new address.
  4. Click Change.

After that, update your DNS A record so the domain points to the new IP address, if the DNS lives elsewhere.

If it fails

  • Check for typos.
  • Make sure the address is routed to your server. Ask support to confirm.
  • Check that the address is not used already.

Quick recap

  • You need root access and an IP from your provider.
  • In WHM, open IP Functions and click Add a New IP Address.
  • Enter the address and subnet mask, then click Submit.
