where does latest dhcp options store?

[Edward DeLargy]

Morning,
            Hope this helps:
             The dhclient lease information should only be stored in the
var/lib/dhclient folder. You should rm -rf * inside that folder to totally
clear old info. Also, depending on your dhcp config you may find traces
inside the network-scripts for the particular interface. A service network
restart should clear anything out after you remove all old files. Those are
the only two places I can think of that cache dhclient lease information.
If you don't remove the old options eventually the old address could pop
back in due to the TTL set in your primary dhcp.conf file.
