Hi,
Unfortunately, what you want is impossible. The smallest entity in
the DNS is the reverse mapping of a C-net. You must ask the "real"
owner of the 166.1.199.IN-ADDR.ARPA zone to add reverse mappings for
your IP addresses.
Meta-answer: subscribe to the bind mailing list
bind-request@uunet.uu.net)
Regards,
Frank
