Lease Parser saves lease states from an ISC DHCP server in a
MySQL database, making it possible to tell which MAC
address owned an IP at a particular time. If you need to track
down a DHCP user for any reason, such as an abuse complaint
for actions weeks beforehand, you can simply search the
database via the Web form for the IP during the time in
question. Then, search on the MAC address you obtained to
see if the system is still on the network and what it's current IP
is.
