Got it! You’re the winner here. I just setup both of my zones the name way and obviously AT&T changed the way they did RDNS entries from when I got a /25 last November and this second /25 in June. Oh well!
Now I am running into the challenge of Route53 does seem to support creating an authoritative zone for "128/25.168.207.107.in-addr.arpa.” It changes it to "128\05725.168.207.107.in-addr.arpa.” every time… *sigh* If it isn't one thing its something else.
Which is "128925.168.207.107.in-addr.arpa." when fed into a domain name parser. DNS escapes sequences are DECIMAL not OCTAL. I suggest that you log a bug report. 128/25.168.207.107.in-addr.arpa. == 128\04725.168.207.107.in-addr.arpa RFC 1035 \DDD where each D is a digit is the octet corresponding to the decimal number described by DDD. The resulting octet is assumed to be text and is not checked for special meaning. That said '/' is not special to DNS parsers and shouldn't need to be converted to \DDD.
