Help with Linux and DHCP

[warlord at MIT.EDU (Derek Atkins)]

DHCP, by default, wants to renew the same IP Address.  Indeed, unless
there is a particular reason why, the DHCP server will give you the
same IP address as well.

I guess I don't understand what you are trying to do.  The DHCP client
will automatically renew the lease for you.  All you need to do is
down the interface if you want to disconnect.  There is no supported
way in the DHCP protocol to 'release' a lease at the server.
