Linux: How to find your DHCP server address and server/client settings

To look at your DHCP settings in linux do the following:

cat /var/lib/dhcp3/dhclient.leases

If you are using multiple NICs then it is best to cd to /var/lib/dhcp3/
and ls what .leases are there.

For Windows users this is similar to ipconfig /all.
The .leases file actually show more information though.
