I don't really need them, right now, I was just surprised I didn't get them 
as they were provided by the author. nameservers.

In a couple of years ICANN will run out of IPv4 addresses, a year or two later 
the regional registries like RIPE will too.

So it's wise to look into it even more then we have done in the past.

So I've been looking at it from the perspective of what will happen if you
really can only get an IPv6-address, because there are no IPv4-addresses
available anymore and I have to say I would use the same word DJB used
to describe it: mess

DNS is not doing much better than a lot of the other fields, so it seems.

A non-forwarding recursive DNS-server will need an IPv4-address to get any
names, because for example the root-nameservers don't even have any IPv6-addresses.

It seems this alternative http://www.orsn.org/ now does have it. Well, that's a start.

This I understand.
