How do I release an Ip address from a cisco DHCP pool
I have a machine that will not release its ip address. It gets it address from DHCP server setup on cisco 2600 router. I have had the user turn the machine off then back on and it still gets the same address. The machine is setup for DHCP. I even set the DHCP lease on the router to 0 0 1.
clear ip dhcp binding * (clears all)
clear ip dhcp binding X.X.X.X (clears specific)
clear ip dhcp binding X.X.X.X (clears specific)
what ikalmar posted is a how to create a reservation but if you want the binding deleted so that another device can get that address or so that your laptop gets a new address use what I put. Also as a note there is a chance if it is the next address in the pool and no other devices request an IP it may still get that IP.
clear ip dhcp binding ?
* Clear all automatic bindings
A.B.C.D Clear a specific binding
Here is the output of the command taken from my 2621 at home.

I excluded the address x.x.x.244 they were using and I also did a clear ip dhcp binding on the address. The user still gets the same address when they reboot. I excluded the address because I want to make it static for a polycom video unit.

ok, if you want to use DHCP use my suggestions.....
Not sure why I referred to it as a laptop must be residual from another thread. Sorry again.
