Forcing DHCP on Ubuntu Server

[Robert Dailey]

Hi,

I'm using Ubuntu Server 8.04. I configured my router's DHCP to always
give my router a static IP. Because of this, I need to configure my
server to always bind its domain name to the DHCP acquired IP address.
Is there a way to do this? Currently I am not sure if it is using
DHCP, I think it's using a static IP (which I don't want).

Thanks for your time.
