I have configured a DHCP server on Windows Server 2008 R2, I have designated a range 0.101 - 0.252, since our WIFI is also on the same network DHCP has ran out of awaylable IPs. DHCP lease retension is 8 days, so some IPs that were used by guest connecting to WIFI are locked even though they are not being used. Is there a way to release unused IP address from DHCP?

Thank you,

Sergey

To keep DHCP simple, you could drop the lease to 1 day - this would clear unused regularily.

An alternative would be to restructure your DHCP scope to allow 2 ranges (one for wired and one for WiFi).

This would involve much more work.

If you know of any that arent in use - you can manually delete them out of DHCP
