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 42 domains are known to be IPv6 glue-enabled: .at .at, .au .au, .ba .ba, .be .be, .biz, .ca .ca, .ch .ch, .cl .cl, .cn .cn, .com, .cx .cx, .cz .cz, .de .de, .dk .dk, .edu, .es .es, .eu .eu, .fm .fm, .fr .fr, .gg .gg, .gs .gs, .hu .hu, .ie .ie, .in .in, .info, .je .je, .li .li, .lt .lt, .lu .lu, .me .me, .mobi, .name, .net, .nl .nl, .no .no, .nz .nz, .org, .se .se, .travel, .tw .tw, .uk .uk, .us .us.

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.



This list also includes a flag if the registrar supports DNSSEC. For easy recognition the ones not supporting DNSSEC are marked in orange in the DNSSEC column as they do support IPv6.

For a full list of .org registrars supporting DNSSEC see PIR's .org Registrar list.

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 with a nameserver with IPv4 address and an IPv6 address 2001:db8::53, the registrar for .com will have:

$ORIGIN com.
@		SOA	...
@		NS
@		NS

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

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