Assign a dedicated IP to Sub-domain

By default cPanel supports the usage of one dedicated IP per account. You can get around this by editing few files on the cPanel server, Please check the same below

• Configuration file of a domain is stored under /var/cpanel/userdata/<username>/ directory,  so for a sub-domain please edit /var/cpanel/userdata/$USER/$SUBDOMAIN.$DOMAIN  change the IP value to a new ‘dedicated’ IP

# vi  /var/cpanel/userdata/$USER/$SUBDOMAIN.$DOMAIN.COM

change the value of the option “IP” to the dedicated IP

• Now one you edit the file and you need to rebuild Apache configuration.

 # /scripts/rebuildhttpdconf

• 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.

# vi /var/named/domain.com.db

and change the A record set for the sub-domain to the dedicated ip we assigned and restart named service

• Edit /etc/domainips and add an entry for that sudomain to point to the IP

dedicated ip>: subdomain.domain.com

• Save the file and rebuild the IP pool

# /scripts/rebuildippool
