Hi
Could anyone tell me, how to configure XP with site-local IPv6 only
address? I removed tcp/ip from network properties and installed tcp/ip v6.
But there is still 6to4 interface. I want to configure XP Pro as ipv6 only.
I appreciate your help.
The 6to4 is an automatic tunneling mechanism to permit access to
the IPv6 internet even though you do not have a native IPv6 routed
environment.
Automatic 6to4 tunneling set up via MS's 6to4 router.
You will get a 2002: address.
MS is trying to push towards IPv6, mostly to loose NAT and re-gain
end-to-end connectivity, mainly for it's p2p platform.
Google on '3 degrees'.
Because their p2p platform is v6 only, MS has to push some migration
strategies heavily.
If the IPv6 stack doesn't pick up a native (global unicast ) IPv6 address
from someplace( manual config or from router announcements ) then it will
fall back on 6to4. Even without you entering anything, it will
auto-configure a tunnel to 6to4.ipv6.microsoft.com [ 131.107.33.60 ] and
pickup a 2002:: address.
If that fails, perhaps due to NAT, then it will use a last-resort mechanism
to gain IPv6 connectivity called Teredo. ( NAT traversal IPv6 tunnel. )
There's a bunch of whitepapers on MS site.
None of this should prevent local communication using link-local or
site-local addresses.
Although XP supports IPv6, I regard that as mainly for accessing the
IPv6 internet, not for all the LAN functions.
Personally, I run dual-stack and have IPv4 on the LAN too, because I
couldn't make my win2k3 domain work properly with only IPv6.
I don't think all the network components are IPv6 capable yet.
I don't think its time yet to run a Windows network in IPv6 only.
In time...
