I am glad they delegated correctly for you. Take a look at the delegation for 128.95.205.63.in-addr.arpa if you want to see what SBC did for mine. For extra fun and laughs, take a look at what SBC's nameservers return when queried. And they have refused multiple requests to lose the pbi.net nameservers.

In this example W is the base IP of the network (ie: 0,8,16,24,32,40,48, etc.) and (W+n) should just be a number and not have parentheses or a plus! PCI/SBC will add the following to their zone files... W.X.Y.Z.in-addr.arpa. IN NS <your-nameservers> W.X.Y.Z.in-addr.arpa. IN NS <your-nameservers> W.X.Y.Z.in-addr.arpa. IN NS <your-nameservers> In my case they did NOT list PBI/SBC as a "NS" for that specific zone, hence it always comes over to my boxes. Then PBI/SBC will add this in their zone files... (W+0).X.Y.Z.in-addr.arpa. IN CNAME (W+0).W.X.Y.Z.in-addr.arpa. (W+1).X.Y.Z.in-addr.arpa. IN CNAME (W+1).W.X.Y.Z.in-addr.arpa. (W+2).X.Y.Z.in-addr.arpa. IN CNAME (W+2).W.X.Y.Z.in-addr.arpa. (W+3).X.Y.Z.in-addr.arpa. IN CNAME (W+3).W.X.Y.Z.in-addr.arpa. (W+4).X.Y.Z.in-addr.arpa. IN CNAME (W+4).W.X.Y.Z.in-addr.arpa. (W+5).X.Y.Z.in-addr.arpa. IN CNAME (W+5).W.X.Y.Z.in-addr.arpa. (W+6).X.Y.Z.in-addr.arpa. IN CNAME (W+6).W.X.Y.Z.in-addr.arpa. PBI/SBC did not do the W+7 entry for me but they did do the W+0 entry. :-) That all said, you just need to add one zone "W.X.Y.Z.in-addr.arpa" on your side. Why is this confusing? Because if you got the same email as I did... they didn't even come close to explaining it this way and hence why your worried about the recurse on the NS's. Contact email address I have in my files for PBI/SBC DNS are... "HARPER, LACONTRIA (SBIS)" <lh6712@sbc.com> DESC Central <DESCCentral@sbis.sbc.com> Note that I don't work for SBC, I just use an xDSL line at home.

Greetings all,
Anyone have an SBCIS (AS7132) contact with DNS clue? I'm being told it's "company policy" that they list their nameservers as authoritative for reverse DNS on space assigned from their netblocks. IOW, they "delegate" by creating NS RRs that point to the correct NSes _and_ NS RRs pointing to their own.
It gets better. Like all good "authoritative" NSes, their NSes disallow recursive processing. Is it truly company policy to screw up reverse DNS for downstreams who run their own?
Wanted: AS7132 contact who understands the concept of lame servers, why they are bad, and is willing and able to help do something about it.
