All the IP address from the DHCP leases

Excellent. I've still got installs of dhcp-status.cgi around (yuck), and a
few uses of dhcpd-pools. I was super excited about Kea when I heard about
it. On paper, it is everything I've ever wanted - DHCP with a relational
database back-end!! So promising. Unfortunately, the handful of times
that I've approached using it, it has been a disaster. I tend to do a lot
of vendor and option 82 matching, creating classes and pools. The last
time I looked at Kea, those features just weren't there. I've written a
bigger application that actually does store all config information in a
MySQL db, but then I'm re-writing the dhcpd.conf file and associated
includes upon each change. That also necessitates restarting the daemon
with the application. It is kludgy at best, but it works. ISC DHCP is
amazing, don't get me wrong. It is so solid. I just wish it had some better
