OT: need SBCIS (7132) contact with DNS clue

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.

Cheers,

  Eddy,

  If you have an xDSL line with static IP's on a /27, then PBI/SBC will setup the DNS as follows.  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 at sbc.com>
          DESC Central <DESCCentral at sbis.sbc.com>

  Note that I don't work for SBC, I just use an xDSL line at home.
