Here is original post

My isp has delegated authority for a small address block back to me,
so I
can run my own reverse dns. If I query for one of those addresses athttp://www.dnsstuf.com, it returns:

Reverse DNS for 209.118.83.210
Generated by www.DNSstuff.com
Country: UNITED STATES

Preparation:
The reverse DNS entry for an IP is found by reversing the IP, adding
it to
"in-addr.arpa", and looking up the PTR record.
So, the reverse DNS entry for 209.118.83.210 is found by looking up
the PTR
record for
210.83.118.209.in-addr.arpa.
All DNS requests start by asking the root servers, and they let us
know what
to do next.
See How Reverse DNS Lookups Work for more information.

It seems like his delegation record, is translating all requests and
injecting 8-29 as the 4th octet.

Netware's named.nlm returns a name error when given
210.8-29.83.118.209.in-addr.arpa. as a query.

My isp says the 8-29 is valid syntax. I've looked at my cricket DNS
and
BIND book(4th ed), and can find something similar on page 239, but the
n-nn
is then the last octet.

Can somebody clarify this?

Oh, I am running named.nlm 5.10.09 4-29-2003 on nw6sp3.

What is the address block and subnet mask?
