Hi
Chrysalis is correct for ptr so if not delegated to you for full control, you need to ask aaisp to set a ptr
The question is why would you want a ptr and/or AAAA dns record public for a mobile device, using its usually permanent ipv6 address.
If you check your ipv6 from settings, Wi-Fi information, at the bottom should be 3 ipv6 addresses
1 is usually permanent and contains your device Mac addrsss
1 is a privacy ipv6 used for showing outside world your ipv6 address - this changes
1 is normally local-link
You would use the Mac associatiated ipv6
I would advice you do not create any public records for this ipv6 address
Many thanks
John
