Define huge -- it's already pretty huge today.

Why ?

DNS is a labelling mechanism, as has been pointed out before.
I don't think people care about assigning meaning to
"www.u8erbjsdhdfdsdf.com".

And we don't because the idea was to have a labelling mechanism
that was distinct from the addressing mechanisme. Nothing more.

Because it's not DNS anymore ?

But it's not the same protocol and architecture is it ?

The second part may be interesting, but I still fail to see how
the existing DNS architecture will not be adequate for IPv6.
