Question: When I am adding domain, I receive an error "System does not have any free IP address available. Proceed with Name Based Domain setup."
If the plan under which the domain is being setup contains dedicated IP address but free IP address is not available on the server then you will receive this error presented with Add Website button.
"System does not have any free IP address available. Proceed with Name Based Domain setup."
This message indicates that due to unavailability of IP on server, the domain cannot be setup on dedicated IP. If you click "Add Website" button on the interface then the domain will be setup on shared IP.
To avoid this error, you need to make sure that enough free IPs are available on the server when an IP-based site is created.
