A little better. So what's the difference between 6to4 and 6in4? Isn't 6in4 what HE uses?
I haven't used 6in4 so I couldn't tell you. 6to4 is a stateless tunnelling protocol. You have a dual-stacked router. It has an IPv4 address, 1.2.3.4. Therefore it supports a 6to4 IPv6 network numbered 2002:0102:0304::/48. Somebody tries to send a packet to 2002:0102:0304::1, it goes to a 6to4 router which encapsulates the IPv6 packet in an IPv4 packet and sends it to 1.2.3.4. 6to4 is handy as a toy or for experimenting, but it relies on a loose network of generous volunteers who, while generous, are neither generous nor numerous enough to support production traffic. -Bill -- William D.
