Well, I’ve managed to knock down one of the tasks that’s been on my “TODO” list for a while, thanks to finding someone building PDNS debs from git.

Background

I live with another geek. When we moved in together, both of us had our own domains, with DHCP servers giving out addresses for the computers we own. As we brought the computers together, the easiest solution was to run as normal, but turn off the “authoritative” function of the two DHCP servers. By doing that, both servers see the DHCP request; one will not know the host, so won’t respond, allowing the other one to supply an address. It was a little clunky but it worked.
