Re: Why do the 6to4-6bone relays work so badly? Is itpossible to use 2002:c058:6301:: with XP?

I'd like to point out that the usage of 6to4 addresses built into
Windows XP is not the usage described in the Proposed Standard
for 6to4 (RFC 3056), which talks about 6to4 *routers*. Nobody has
published a document describing host usage of 6to4.
