-----BEGIN PGP SIGNED MESSAGE----- Hash: SHA1 Hello All, I am having difficulty resolving Reverse DNS for 167.216.129.170, and I'm not entirely certain why. If I just do a dig -x 167.216.129.170 I get:
; <<>> DiG 9.7.3 <<>> -x 167.216.129.170 ;; global options: +cmd ;; connection timed out; no servers could be reached If I dig -x +trace 167.216.129.170: ;; Got answer: ;; ->>HEADER<<- opcode: QUERY, status: NXDOMAIN, id: 28671 ;; flags: qr rd ra; QUERY: 1, ANSWER: 0, AUTHORITY: 1, ADDITIONAL: 0 ;; QUESTION SECTION: ;167.216.129.170.

This is impacting my ability to receive transactional emails from this IP address in particular. My DNS server is running Bind 9.7.3 on Debian Squeeze. I thought perhaps my DNS server was being blocked, but that wouldn't explain the NXDOMAIN I don't believe. I apologize in advance if this is something simple and/or obvious, but can anyone explain what is happening and/or how to correct it? Many thanks in advance!
