Post subject:  Linode DNS manager and AAAA records
Hello everyone,
I just enabled ipv6 for my node (london facility) and everything is working fine. I completed successfully every suggested test in the networking guide and configured the ip6tables rules working together the existing iptables rules.
Now I need to enable IPv6 DNS resolution for my domain (so far just 1 domain), managed by Linode DNS manager.

My problem is that I can't find the "Add a new AAAA record" link in the DNS manager console, but only the "Add a new A record" link.
I suppose it is possible since the header of the dedicated list says "A/AAAA records".

Can you help me?

Thank you

They can be added under the "A" section. The Manager determines if the entry should be an "A" (IPv4) or "AAAA" (IPv6) record.

You mean this: http://library.linode.com/networking/ipv6? Which I find rather brief and doesn't mention ip6tables. Other sources?

The output of ufw -status on my linode is:
Code:
Status: active

To                         Action      From
--                         ------      ----
22                         ALLOW       Anywhere
80                         ALLOW       Anywhere
443                        ALLOW       Anywhere
22                         ALLOW       Anywhere (v6)
80                         ALLOW       Anywhere (v6)
443                        ALLOW       Anywhere (v6)

Does this means it is ok?

That cleared things up a bit. Do you have to add the square brackets or the /64 at the end when entering an IPv6 record?
If I understood correctly you have to add an AAAA record for every A record, meaning for every site and every subdomain: www.example.com, mail.example.com, pma.example.com, stats.example.com, ....

Thanx,

Looks good.

Nope, just the IPv6 address itself, e.g. 2600:3c03::13:3f02 ... the brackets are just a convenience for host:port notation. You may (or, per RFC 5952 sec 4.2.1, MUST) compress out the zeros to the fullest extent possible.

Well, you don't have to do anything... :-)

But yes, anywhere you want an IPv6 address to appear, you'll need to add an AAAA record. Same as for IPv4 addresses and A records. If you have more than a few handfuls, this is a good opportunity to hone your Linode API skills.
