That sounds good to me. The only thing missing is the 'arithmetic' bit on
the generated host name / IP address.

In your example above, I would want (for example)

192.168.202.50 - dyn-1
192.168.202.51 - dyn-2

etc.

This is possible in bind using the syntax I posted earlier, but isn't (yet)
in dnsmasq.

It's hardly the end of the world if I have to manually enter each one
though, so I wouldn't push for this change too much if it turned out to be
particularly difficult or generate any strong objections.
