win_dns_record: option to automatically create PTR record about community.windows HOT 6 OPEN

Since the -CreatePtr option is available with the creation of an A or AAAA record, I think we can make this a boolean option. I already have the code partially done for this. Thoughts?

This feature will be added any time in the future?

I'm here for the same request, as the lack of this feature is either making me write some awful block/rescue logic to try to figure out which reverse zone I need to create the PTR in, or I'm rewriting my own module to use Add-DnsServerResourceRecordA so I can use the -CreatePtr flag.

While this sounds great at a surface level, I'm having trouble seeing how this could be done while remaining idempotent (which Ansible requires).

Although the DNS Manager UI can help you to create mirrored PTR and A records at the same time, the resulting artifacts aren't actually linked in any way other than common convention. That's a pretty terrible thing for any algorithm to depend upon, especially when idempotence is required (which it is here).

Eg consider the update case -- where you change the IP address on an A record using an Ansible task with the proposed ptr: yes. On the PTR side, does that mean you only create the new (matching) record? Or does it also imply deleting the old (no longer matching) record? What about cleaning up other stale PTRs that refer to the same hostname? How could it even find them efficiently given that DNS record values are unindexed?

I'm guessing similar problems exist anywhere else where idempotence is required of things that only agree by convention.

Anyway, I'm happy to be proven wrong here; but I think we're going to need much greater clarity on how idempotence can remain enforced around the various corner cases. This shouldn't be a "creation-time only" thing.

Could you share your code for ptr you have? It would be very helpful for everyone

This option would be great. Any plans to add this flag in the near future?
