Unless this has changed while I wasn't looking (quite possible:-),
innd's method of checking hostname / IP addresses of connecting clients
differs from that of most other servers: Rather than doing a reverse
lookup of the IP address at connection time and checking that against
the allowed hostnames, it does a forward lookup of all allowed hostnames
at startup and reload time, and at connection time just checks the
connecting IP address against the list saved from that lookup.

There are several advantages to doing it this way; one drawback is that
wildcards in hostnames are fundamentally impossible, though.
