We are the primary DNS servers for the ben.edu domain. We seem to be having an issue with an AT&T server that is responding with incorrect A records for www.ben.edu<http://www.ben.edu> and ben.edu.
What it SHOULD be the response: nslookup www.ben.edu Server: 63.250.224.66 Address: 63.250.224.66#53
www.ben.edu canonical name = ben.edu. Name: ben.edu Address: 38.100.120.100
What 12.127.17.83 is responding with:
www.ben.edu Server: tbru.br.rs.els-gms.att.net Address: 12.127.17.83
Non-authoritative answer: Name: www.ben.edu Address: 208.91.197.132
Looks to be right now. Did you wait a full day for the old records to timeout of the caches? ; <<>> DiG 9.10.0pre-alpha <<>> www.ben.edu @tbru.br.rs.els-gms.att.net ;; global options: +cmd ;; Got answer: ;; ->>HEADER<<- opcode: QUERY, status: NOERROR, id: 8202 ;; flags: qr rd ra; QUERY: 1, ANSWER: 2, AUTHORITY: 0, ADDITIONAL: 1 ;; OPT PSEUDOSECTION: ; EDNS: version: 0, flags:; udp: 4096 ;; QUESTION SECTION: ;www.ben.edu.

This appears to be affecting only iPhones and iPads on the AT&T network. Is anybody else having problems with this? Are there any AT&T people on this list that can help?
