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 <mpeter...@apple.com> wrote: > I can now confirm that Christopher is right about everything (not that I > had any doubts!
