Which IPs from the range are assigned to DHCP enabled clients

Hi All

dhcpd.conf has a range of IPs sa for example(

So this is the range of IP addresses the server will issue to DHCP enabled PC clients booting up on the network

How do i know which IPs are being used or which IPs from the range are assigned to dhcp enabled clients ?

DHCP server runs out of IPs

Hi all
When DHCP server assign a IP to dhcp enabled clients it reserve IPs for the time specified in the dhcp.conf file and I have set it to 24 hours.

Very often DHCP server runs out of IPs so is there a way to release the IP from the client which are not pingable or down?

Or is there a script to handle this situation?

Please let me know.

You could set your dhcp lease time to a shorter duration

Can I delete the entry from dhcpd.leases for the host which says "binding state free" ?

It is not recommended, and I am not sure what the ramifications for that would be. You could restart the service after making the changes
