By default, cPanel supports the usage of one dedicated IP per account. However, you can get around this by editing just a few files on the server. Here are the steps:
1. Edit /var/cpanel/userdata/$USER/$SUBDOMAIN.$DOMAIN for each subdomain (for addon/parked domains you’ll usually edit the file for the subdomain associated with the addon/parked domain) and change the ip value to a ‘dedicated’ ip.
2. Run /scripts/rebuildhttpdconf
3. Edit the dns zone for the subdomain (which will likely be attached to the parent domain) and update the a-record to point to that IP as well. Then syncronize the zone out to the DNS cluster, if one exists:
/scripts/dnscluster synczone <parentdomain>
4. Edit /etc/domainips and add an entry for that sudomain to point to the IP and run /scripts/rebuildippool to make sure the IP is marked as taken.
