Ipv6 nameservers missing?

[jojolafrite]

I have linked an Ipv6 address to my main Ipv4 web server address in IP management at Admin level. All the records have been created for an existing domain at user level (admin too).

Nevertheless, AAAA records where missing for the ns1 & ns2 nameservers. I expected the following records below that would mirror the A records of ipv4 nameservers:

ns1.mydomain.com. A xxx.xxx.xxx.xxx
ns2.mydomain.com. A xxx.xxx.xxx.xxx

i expected something like that for ipv6:

ns1.mydomain.com. AAAA xxxx:xxxx:xxxx:xxxx:xxxx:xxxx
ns2.mydomain.com. AAAA xxxx:xxxx:xxxx:xxxx:xxxx:xxxx

I have added it manually to mirror the A records for my ns1 & ns2 server.
