For CentOS 5, the command:
grep dhcp-server-identifier /var/lib/dhclient/dhclient-eth0.leases
or for CentOS 4, the command:
grep dhcp-server-identifier /var/lib/dhcp/dhclient-eth0.leases
will list the dhcp server(s) that the system recently got its IP address
from. The most recent dhcp renewal should be at the bottom of the list.
