Hi Scott:

I appears as if DNSSTUFF gets confused by classless reverse lookup
delegations?

http://www.dnsstuff.com/tools/ptr.ch?ip=12.45.239.55

says:

Searching for PTR record for 55.239.45.12.in-addr.arpa at
CBRU.BR.NS.ELS-GMS.ATT.NET.:  Reports 55.239.45.12.in-addr.arpa.

which is incorrect. According to RFC 2317 it should have said:

Searching for PTR record for 55.239.45.12.in-addr.arpa at
CBRU.BR.NS.ELS-GMS.ATT.NET.:  Canonical name
55.32/27.239.45.12.in-addr.arpa.
Searching for PTR record for 55.32/27.239.45.12.in-addr.arpa at
CBRU.BR.NS.ELS-GMS.ATT.NET.: Got referral to AUTH00.NS.UU.NET.
Searching for PTR record for 55.32/27.239.45.12.in-addr.arpa at
AUTH00.NS.UU.NET.: Reports mail.dextershoe.com.

etc.

(Let's overlook for a moment, that AUTH00.NS.UU.NET currently is actually
missing that zone <G>)
