Is any harder than,

$ORIGIN 168.50.204.in-addr.arpa. $GENERATE 0-15 CNAME $.0/28 0/28 NS ns.mydomain.org.

That's the whole point. They are equivalent, but the former doesn't force you to invent your own naming scheme or use CNAMES (if using A records in in-addr.arpa domains is distasteful, then imho using CNAMES is even more distasteful, not to mention RR's containing the "/" character). --Adam
