Well how are you connecting ? Thru ethernet ? You can try a ifconfig eth0 down then a ifconfig eth0 up to bring it back up. Not for sure though if it will get a new IP from the previous one.

Whats the reason why you want to release the IP ?

I guess the IP will be the same as you get after you release & renew, depending on the rules set on the DHCP server on the duration of the IP lease period reserved for your ethernet MAC address. I believe most ISPs' IP lease-period will be very short.
