Assign single/One IP to multiple domains/Accounts in Cpanel :-
Lets say you have domain1.com, domain2.com, and domain3.com on the same server and you want to keep them as individual accounts while allowing them to share an IP address. This works much is shared hosting
1.) Login to the WHM and click Show IP Address Usage
2.) Find an available IP address that you would like to use and Copy it in a Notepad
3.) Click on Basic cPanel/WHM Setup – Search for The IP address (only one address) that will be used for setting up shared IP virtual hosts.
Setting an IP not associated with this server is possible but not advised. – This should be your primary server IP (Write down this IP for future reference). Update this with the newly copied IP address that you’d like to use and click Save Changes
– Note this does not change any sites to this IP
4.) Click Change Multiple Sites’ IP Addresses
Locate and check the domains that should share this new IP i.e. domain1.com, domain2.com, domain3.com
5.) Click Change IPs of Selected Accounts
6.) Next to each site there should be a drop down box. Select the last option in each drop down box which should read:
0.0.0.0 (main shared IP) where 0.0.0.0 is the new IP for the sites to share
7.) Click Change IPs
You now have a group of accounts sharing the same IP in cpanel!
Important Note– Once you are done Click on Basic cPanel/WHM Setup – Main Shared Virtual Host IP – replace this value with the original Main Shared Virtual Host IP and click Save Changes. If you don’t newly created accounts will receive the IP address that you just setup for a specific group
