Paul- AFAIK, IPv6 is in fact enabled/capable in BIND currently, but no one uses it- IPv6 will be a LONG time in coming to everyone, with the major challenge being a 'transition phase' where devices (routers for a prime example) are able to handle both ipv4 and ipv6...without that, ipv6 is useless outside of 'playing with it locally.' This shouldn't have any effect on name registrations, they will just eventually map to both ipv4 AND ipv6 addresses..

as usual, there has been a bit of a misunderstanding... being a loosely typed language, Engliosh is difficult to communicate in :-0 Names, addresses and DNS are obviously different things. I understand where IPv6 addresses come from (sort of). I understand (sort of) how IPv6 works for DNS records relating names to IPv6 addresses what I was really asking is: in the IPv4 world, name brokers sell names that are then related to IPv4 addresses. Legality of the name choice etc. is generally owner onus... Is there a similar sort of (or coincident) naming authority for IPv6 based names? example. if I operate a network, boxen1.example.org, boxen2.example.org, etc., as an IPv4 address space and a second coincident network, boxen1.example6.org, boxen2.example6.org, etc., as an IPv6 based address space, where does the authority to allocate the IPv6-network based names reside? the technical side of it is clear... someone somewhere needs to keep a track of the names... anyway, this is straying somewhat from the core subject matter of this list...

I don't know for sure here, so please take this with a grain of salt: IPv6 addresses are represented by instead of A records in DNS nameservers.

You would normally not be able to influence this, because it is deeply intertwined with the routing protocols that all network operators use to transmit data on the Internet.

There can be only one registered owner of any given domain name and that domain name space could be either v4 or v6 at the discretion of the owner.

Re: Ooops - Re: while I have your attention... Names, copyright and IPv6
if I operate a network, boxen1.example.org, boxen2.example.org, etc., as an
IPv4 address space and a second coincident network, boxen1.example6.org,
boxen2.example6.org, etc., as an IPv6 based address space, where does the
authority to allocate the IPv6-network based names reside?
AFAIK, there is only one DNS system, which is designed to serve
names for both IPv4 and IPv6. It is the client who asks either
for A records (IPv4 resolution) or records (IPv6 resolution),
from the SAME set of DNS servers.
Let's assume that you want to operate *.example.org as IPv4 and
*.example6.org as IPv6 networks. You would have two domains
in the .org TLD:
example.org - NS ns1.example.org
- NS ns2.example.org
example6.org - NS ns1.example6.org
- NS ns2.example6.org
It is important to realize that ns1 and ns2 must resolve
to IPv4 addresses for both example.org and example6.org.
Now you could populate the DNS maps of ns{1,2}.example6.org
with records holding IPv6 addresses, and the DNS maps
of ns{1,2}.example.org with A records, holding IPv4 addresses.
Nothing prevents you from doing both on the same domain!
example46.org - NS ns1.example46.org
NS ns2.example46.org
ns{1,2}.example46.org could contain both A and records,
like, say:
hybrid A some-ipv4-address
hybrid some-ipv6-address
The host hybrid.example46.org would have an IPv4 and an
IPv6 address (they don't need to overlap!).
Now the clients' resolver library would generally ask
for A records, if it should resolve hybrid.example46.org.
It would therefore obtain an IPv4 address from
ns{1,2}.example46.org for the host name hybrid.example46.org.
A client could still ask for IPv6 addresses, e.g.:
% host -t hybrid.example46.org (ask for IPv6 address)
% host -t a hybrid.example46.org(ask for IPv4 address)
% host hybrid.example46.org (same as host -t a ...)
the technical side of it is clear... someone somewhere needs to keep a track
of the names...
You are responsible for keeping track of the names
under *.example.org, *.example6.org, *.example46.org.
There is no such thing as an IPv6[-only] domain name.
If you asked about PTR records, this would be more
interesting... [Hint: ip6.arpa.] ;-)
anyway, this is straying somewhat from the core subject matter of
this list...
Well, yes...
