I want to check on the reserved leases (called "fixed-address" in the config files) of my dhcpd. To get all the info about the free dynamic ips is no problem, but the reserved one that get written to a MAC address are not shown in any file that I could imagine to be connected to dhcpd.
Best would be if I could see if the reservation is active and if not, since when it has not been used. That way I could declare that device as gone and mark the reservation as free for new ones.
For the normal leases I use this answer with the python script: How do I show active dhcp leases
That works pretty good as long as it is not a reserved one.
Maybe someone out there has an answer to that.
