Please don't confuse private addresses with NAT. The idea of private
addresses existed long before NAT. A private address is just that, it
doesn't connect to anything. NAT then took advantage of those address
blocks. Private addresses are not the problem (there are some with
IPv6 too), NAT is.
RFC1918 is dated 1996, and obsoletes 1597 from 1994. NAT was discussed
at least as far back as 1992. (RFC1380, section 2.2.3, paragraph 3).

I recall talk about using IP on amateur radio in the early 90s. IIRC,
they were saying to use the 10. block as that was assigned to the U.S.
military and not connected to the Internet and so was safe to use.

Funny you should mention that. I recently watched a video by someone
on Microsoft's XBOX team, talking about the problems NAT causes for
games and how the XBOX will always try to use IPv6, even if it has to
set up a tunnel to do so. It will only use IPv4 as a last resort.
Same as openSUSE then. Except for setting up a tunnel. Funny, when I
googled "xbox ipv6 tunnel", the first page was all about teredo ipv6
tunnels and the trouble in getting them to work :-)


Well, it is from Microsoft... ;-)

I had a 6in4 tunnel up for 6 years. Worked well.
