At the most receint NANOG some methods of delegating DNS (in-addr.arpa's) on
non octet boundaries was disccused. If I remember correclty
there were two parts to this, regarding delegating individual
records, and some other process.
We, JPNIC, are recommending ISPs to use a method proposed in the
draft-degroot-classless-inaddr-00.txt when ISPs allocate prefixes
longer than /24 out of their block.
Is there any known problem in this method?
