[dns-operations] Reverse Lookup speedup

I've very interestingly read the thread about NetBSDs new root slaving,
and that some are pissed off by this, and grabbed the hint that loading
the root zone from ftp.internic.net is also possible and I immediately
did this for one heavy loaded DNS server.
As we primarily do mail servers, which tend to do a big amount of
reverse lookup during spam checking, I was wondering if there's some
similar way of loading (or slaving) a reverse lookup root zone. Sorry
if this is stupid, I still do not understand how reverse lookups are
done. Is that just the .in-addr.arpa zone that would need to be loaded,
and if yes, where could I automatically get it from?
