You don't need any $ORIGIN's in your zone files at all; they're completely
optional. The identity of the zone itself is the default origin, e.g. if
you load a zonefile as 101.168.192.in-addr.arpa, then
101.168.192.in-addr.arpa is the default origin. $ORIGIN directives just
save a little typing if you're manually maintaining a zonefile and have
"clumps" of records in a particular subdomain or, less likely, a bunch of
long RDATAs (right-hand-side's) which all happen to be clumped in a
certain domain. But then, nobody maintains zonefiles manually any more, do
they? :-)
