There exists an automatic IPv6-in-IPv4 tunnel mechanism, where the IPv4 address
is used to give an automatic IPv6 address. All you need to do is add two lines
to the ifcfg-$DEVICE file:
redhat-config-network should do this for you, possibly even by default for
public IP addresses if IPv6 is enabled system-wide.
This would be FC2
Personally I would like to suggest adding:
by default to /etc/sysconfig/network.
David, shouldn't native IPv6 be the default, and
6to4 a configuration option in r-c-n?
Native IPv6 happens by default -- if there's a route adversiting
daemon on the subnet and ipv6.o is loaded, you'll get your native IPv6
It's only really 6to4 which needs configuration.
Well IPv6 only happens if ipv6 is enabled (eg with NETWORKING_IPV6=yes
for all capable interfaces or IPV6INIT=yes for individual interfaces).
My comment was about IPV6TO4INIT=yes, which I don't think should
be set by default for interfaces. Though of course it could be
an r-c-n config option. Am I missing something?
You're right. Native IPv6 should be on by default, and 6to4 should be
a checkbox in r-c-n.
