I actually do have the bare box--unless they've done something terribly tricky that has me fooled. My netstat -i shows no information for the alternate IP addresses. (eth0: 1500 0 --no statistics available-- BRU). My hosts file shows 216.167.114.244 216.167.114.244-generic.
If I were to rebuild, I'm assuming I'd ifdown and ifconfig the ip address. Can you give me more advice than that?
