Does this mean that I have IPv6? If so, what are these 5 sites that are
on IPv6?
Sure doesn't look like it's configured, just enabled in your OS. In
fact, it doesn't look like IPv4 is configured on that interface
either, which is odd, are you sure that's the interface connected to
your ISP?
Sorry, I assumed it would be obvious that I obscured the real addresses
(since this is a public list, and the addresses are not private ones).
Sorry I didn't think of that. However, there's a lot to learn from
the early 16-bits of the IPv6 address, it tells what kind of routing
the address uses. If it starts with a 2002, then you're just
tunneling your ipv6 over ipv4 to the nearest public gateway.
Yet one of the links there tell me I am coming in via IPv6, but the
address they claim I am using is very different than the one shown
to me by ifconfig. ifconfig says: fe80::2e0:4dff:ffff:ffff/64 (last
two segments intentionally obscured)
fe80 is a link-local address, which probably just means that they're
telling you the address of a nearby router that they can talk directly
with. This is also suggests 6to4 is encapsulating the IPv6.
