Which IPs from the range are assigned to DHCP enabled clients
Hi All

dhcpd.conf has a range of IPs sa for example( 192.168.1.201 192.168.1.220)

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 ?

Thanks

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.
Thanks

You could set your dhcp lease time to a shorter duration

dhcpd.leases (Linux Reviews)

Thanks

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

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
