RFC 2317 does not mandate any particular zone name format - it leaves
that to whoever implements the principle laid out to decide. I have
seen start.z.y.x.in-addr.arpa, start.start.z.y.x.in-addr.arpa,
start/masklen.z.y.x.in-addr.arpa, start-end.z.y.x.in-addr.arpa, ...
and of course it can be pointed outside of in-addr.arpa as well if
need be for some reason. However, the RFC mentions start/masklen as
one possible format for the zone name.
I personally like it - others have different opinions, as searching
this list's (or news group's) archives will show you.

``And indeed people sometimes speak of man's "bestial" cruelty, but
this is very unfair and insulting to the beasts: a beast can never be
so cruel as a man, so ingeniously, so artistically cruel.''
(Ivan Karamazov, in Dostoyevsky's 'The Brothers Karamazov')
