While activating a new account I could see an error
“Your system has run out of available ip addresses, or you do not have permission to use any more ip addresses”
The issue was due to the server running out of spare dedicated IP address
The issue can be resolved in 2 ways
1) Adding additional IP address in server
2) By editing file /var/cpanel/packages/abckhosting which is a package file which is assigned to customers.
SSH to server in question on which account is activated and edit the package file as mentioned
The parameter IP=y needs to be changed to IP=n to get account activated without adding new IP address.
This did help in creating new account without adding additional IP address
