!!!What is 6to4
-6to4 addressing is a type of ipv6
address created by your IPv4 address. It allows you to set up tunnels over the [IPv4] Internet automatically.
+6to4 addressing is a type of [IPv6]
address created by your IPv4 address. It allows you to set up tunnels over the [IPv4] Internet automatically.
The range for this is 2002:<first two bytes of an ipv4 address>:<second two bytes of an ipv4 address>::/16.
This gives you a /48 to play around with, great if you have to put up with [NAT], now all the boxes behind your firewall will have realworld [IPv6] addresses at no extra cost!
