Ooops - Re: while I have your attention... Names, copyright and IPv6

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 

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?


if I operate a network,,, etc., as an 
IPv4 address space and a second coincident network,,, 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...
