I agree with Sparr, this question needs clarification. Are you talking about static vs. DHCP, updating DNS entries on a server, or using DHCP to assign which DNS servers to use? –  KevinH Jun 16 '09 at 22:02

IIRC, automatic IP addresses have been made illegal. You can, however, still use semi-automatic IP addresses.

haha, I just hope that Edgar doesn't think that this is a real answer, and then ask "Why are automatic IP addresses illegal?" –  Mark Henderson Jun 16 '09 at 22:40
    
Really, though. That question will get him further along that the one he originally posed. ;) –  dr.pooter Jun 17 '09 at 13:23

In Windows XP if your asking how to change from a static IP to DHCP

Click "Start" --> Click "Run" --> Type "control netconnections"

Right click on the interface you want to configure --> Select "Properties"

In the box for "This connection uses the following items:" select "Internet Protocol (TCP/IP) --> Click "Properties"

Change the setting under the "General" tab to "Obtain an IP address automatically" --> Repeat for DNS server if needed.

It depends heavily on what OS you're running. It also requires that you get your IP address via DHCP.

In Linux (Red Hat), you'd edit /etc/sysconfig/network-scripts/ifcfg-$INTERFACE. In Windows, you'd go to Network Connections->"INTERFACE"->Internet Protocol->Properties.
