Curious if anyone can tell me, or point me to a link, on how 2002::/16 is actually implemented for 6to4? Strictly for curiosity.
We had a customer ask about blocking spam from their wordpress blog that we host and the spammer was using 2002:af2c:785::af2c:785, which was the first time I'd seen wordpress spam coming from IPv6. Per RFC3964, I'm guessing the 175.44.120.5 is just a relay router, not surprisingly, on the China Net network and the spammer was native v6? I see that net advertised from 6939 (HE) and 1103 (SURFnet Netherlands) from the perspective of my feeds, so that just got me more confused. Thanks, David
