Yep, the notation with the slash used to be ATT's standard method. At my job (where we had some customers with ATT MIS T1 circuits) we transitioned to a web front end for our DNS that didn't allow for the slash, so we had to nudge ATT to allow us to use a dash notation instead for delegations. As far as to what can appear in a DNS entry, you'd be amazed. I encountered a PTR record containing a full URL, http:// and everything; it didn't actually work of course, but bind allowed it to exist. When I tracked down the cow-orker who had entered it, he said he knew it wasn't valid, but he did it that way when the customer insisted it had to be thus. :-D On Wed, Oct 4, 2017 at 11:33 PM, Matt Peterman <mpeterman@apple.com> wrote:
I can now confirm that Christopher is right about everything (not that I had any doubts! Just wanted to confirm all is working!!)
ATT is now following the RFC (apparently has changed since November 2016 and June 2017 allocations and DNS changes) and that Route53 WebUI displays things strangely, however technically works fine on the backend. rDNS is now working properly. Thank you Christopher very much! I learned a lot in the last hour I can sure say that!

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.
I've not messed with route53 but fortunately you are treading on well trodden ground: https://forums.aws.amazon.com/thread.jspa?messageID=674778 < https://forums.aws.amazon.com/thread.jspa?messageID=674778>
have a happy evening! (and I hope that the above works.. again I haven't and can't actually try it)
