If you can justify the need you might be able to get multiple IPs on a business account (although with IP addresses running out it's getting tougher). On a residential account it's a definite no.
Thanks for the reply Currently got my own server at home and was looking at hosting my own dns for 2 domains I currently have. I know it can be done from 1 ip address but thought I would ask about 2. It's all private domains and not business so I'm guessing it's another line or stick with 1 ip
