How do I secure my reverse delegation with DNSSEC? How do I setup a reverse DNS? The Internet is slow now I've enabled IPv6 (Broken DNS servers that don't support AAAA records) Which DNS Registrars allow me to add AAAA glue for my Domain Name Servers?

Which DNS Registrars allow me to add AAAA glue for my Domain Name Servers?

To be able to be fully IPv6 enabled, and not having to rely on IPv4, one will need to have AAAA glue for your domain and its parents. IPv6 Glue for the roots is there, and glue for several TLD's already exist. This page lists which registrars can add AAAA for your own DNS nameservers into the TLD zone, therefor making your domain reachable over IPv6 without a need for IPv4.

Top Level Domains supporting IPv6 Glue

The following 33 domains are known to be IPv6 glue-enabled: .au , .ba , .be , .biz, .ch , .cl , .cn , .com, .cx , .cz , .de , .dk , .edu, .eu , .fr , .gs , .hu , .ie , .info, .li , .lt , .lu , .mobi, .name, .net, .nl , .no , .nz , .org, .se , .travel, .tw , .uk .

For .hu (Hungary) it is enough to add an AAAA record to the nameserver host. They automagically include the glue in the .hu zone by scanning for AAAA records for any registered nameserver for domains under .hu.

.nz (New Zealand) has a list of .nz registrars which support IPv6 glue.

.ca (Canada) has IPv6 Glue support but no registrars are known who can handle it.

What are Glue Records?

Glue though is present at the nameservers that delegate to your zone. These so called "Glue records" have to be published by the TLD operator.

Note that it is of course easy to have AAAA records for your own zone, as you control the records in your zone.

In case of example.com with a nameserver ns1.example.com with IPv4 address 192.0.2.42 and an IPv6 address 2001:db8::53, the registrar for .com will have:

$ORIGIN com.
@		SOA	...
@		NS	ns1.com.
@		NS	ns2.com.

example		NS	ns1.example.com.
ns1.example	A	192.0.2.42
ns1.example	AAAA	2001:db8::53

Because of those two records, the nameservers for .com can tell that queries for *.example.com can be answered by ns1.example.com which can be contacted at 192.0.2.42 and 2001:db8::53. If those records where not there there would be no way to find the IPv4 or IPv6 address for example.com.
