Thanks Michael,
I don't quite understand?
Don't I need to have any dns entries for the domain name I'm going to use
the new IP address for?
My server has 2 NICS installed with separate IP addresses assigned to each
one. 
And under, it will only allow me to add alias IP addresses to eth1.
Ipconfig reports eth0, eth1, eth1:0 and Lo.
Do I even need to do set an alias under System Settings - TCP/IP - Interface
aliases?
And should I remove the second NIC and just use one with alias IP addresses?
Thanks
Tom
