[Declude.JunkMail] Reverse dns help
I asked Ameritech - oops SBC to add a reverse dns entry for me, instead it appears they have delegated rdns to me. I tried http://www.dnsstuff.com/tools/ptr.ch?ip=65.42.199.3 to see what is happening. I don't quite understand the Got CNAME referral to ns2.ostgaard.com (zone 3.0.199.42.65.in-addr.arpa) should this not return (zone 3.199.42.65.in-addr.arpa) ? Is this the correct response, or have they not quite done the delegation correctly? How I am searching: Asking e.root-servers.net for 3.199.42.65.in-addr.arpa PTR record: e.root-servers.net says to go to ginseng.arin.net. (zone: 65.in-addr.arpa.) Asking ginseng.arin.net. for 3.199.42.65.in-addr.arpa PTR record: ginseng.arin.net says to go to NS2.AMERITECH.NET. (zone: 42.65.in-addr.arpa.)

PTR record: Reports that no PTR records exist. Answer: No PTR records exist for 65.42.199.3.

What is happening here is that Ameritech/SBC is using CNAMEs to delegate on other than Class A/B/C boundaries. Is this the correct response, or have they not quite done the delegation correctly? They actually have done it correctly. In this case, you would set up a PTR record for 3.0.199.42.65.in-addr.arpa, which would be the reverse DNS entry for 65.42.199.3. It's a bit confusing, but works. -Scott --- Declude JunkMail: The advanced anti-spam solution for IMail mailservers.
