There are a number of different DHCP clients that run on Linux. Use the command "ps ax" to try to determine what processes are running that might have something to do with your ethernet interface.

DHCPCD is a popular one. Look to /etc/dhcpc for any files that might be there.

PUMP is also a frequent program in use by some versions of RedHat Linux. Run "pump -i eth0 --status" assuming your ethernet interface is eth0

DHCLIENT -- run "locate dhclient.leases" and look into that file if you see that process running.
How can I find the dhcp server on Linux ?

In general, the fundamental task of innovation is to look at the world without the assumptions you normally apply, and look at ways that things could be improved that you wouldn't normally think of changing.

Good luck!
