6in4 is IPv6 encapsulated in IPv4 = protocol 41, typically used in manual tunnelling configuration and also in tunnel brokers and some other type of tunnels. 6to4 is an automatic transition mechanism that uses 6in4 to automatically create IPv6 tunnels using a special IPv6 prefix 2002::/16, appending the IPv4 public address to obtain a /48 for each IPv4 public address. It works very well for peer-to-peer, but it requires 6to4 relays for connecting to end-sites using any other kind of IPv6 connectivity (anything not-6to4).

A little better. So what's the difference between 6to4 and 6in4? Isn't 6in4 what HE uses? -Hammer- "I was a normal American nerd." -Jack Herer On Thu, Mar 3, 2011 at 3:54 PM, William Herrin <bill () herrin us> wrote:On Thu, Mar 3, 2011 at 3:41 PM, Hammer <bhmccie () gmail com> wrote:I need a cheat sheet. nat64 6to4nat 6in4nat etc...6to4 and 6in4 are not NAT. They're tunnels (VPNs) that allow two IPv6 nodes to talk to each other via an IPv4 backbone. nat64 is NAT. It allows IPv6 endpoints to communicate with IPv4 endpoints. nat44 is the IPv4 NAT you're used to. nat444 is carrier NAT (translated once by the customer and once again by the ISP, get it?) -- William D.
