Very interesting topic. I'm including some links for FYI. I know that some
websites are IPv6 enabled and if you are on an IPv4 network, you can't
access them. Others have gateways which can encapsulate IPv4 packets from
outside and allow access to their IPv6 network. However this involves
processing at the gateways and would not be a problem if we all use
IPv6. Most of the the relay routers are only IPv4 and don't even have the
ability to encapsulate IPv4 packet in IPv6 and vice versa to reach the
different network. Now the other question is about what are the other
protocols and applications which can understand and process IPv6 packets.

I might need to set up an FC5 box as a router. I see from the Netfilter

Thanks!

Netfilter (ip6tables) *can* filter IPv6 traffic, it just can't yet
filter packets based upon state (NEW, RELATED, ESTABLISHED, etc.). It
therefore can't do "stateful packet inspection." Unfortunately, the
default Fedora ip6tables configuration, when activated, will cripple
your ability to communicate via IPv6 at all because the ip6tables rules
are nothing more than a clone of the (stateful) IPv4 rules. You'll have
to manually alter /etc/sysconfig/ip6tables to fix this condition. See
https://bugzilla.redhat.com/bugzilla/show_bug.cgi?id=190590 for details.
It doesn't look like anything is going to be done about it soon.
If you're interested in IPv6 in Fedora, the easiest solution is to
establish a free account with an IPv6 broker, like Hexago
(freenet6.net). You'll be given a global address prefix and a daemon
(called tspc) to configure. The daemon establishes an IPv4 tunnel to
the broker that encapsulates your IPv6 packets so they'll pass through
your IPv4-only ISP middleboxes. At the broker tunnel endpoint, your
IPv6 packets will be set free, so to speak, and you'll be able to
communicate to the wider IPv6 internet.
