It works fine.  I use it that way ;>)

Actually, I would quibble with the word "meant".
This classless technique is nothing special -- it makes use of all
standard DNS stuff, so there was nothing "meant" to be there specially
for the classless delegation.

All I did was to use the same ideas for making a separate zone for
the dynamic stuff.


>delegate PART of a reverse-lookup DNS domain

That's *exactly* what my setup does, just ...


>to another server.

*not* to a different server.  There's nothing that says it *has* to be a
different server.

It wouldn't work for that.  I don't think.

This is meant to delegate PART of a reverse-lookup DNS domain to
another server.

E.g., if I have 128.376.999.in-addr.arpa, and I delegate
999.376.128.64/27 to somebody else, I can use this trick to let them
maintain their own reverse DNS.  See RFC 2317s, Classless IN-ADDR.ARPA
delegation.

[Yes, those are illegal IP addresses.  That's so I wouldn't choose
anybody's favourite address.  ;-}]
