6in4
6in4 is an Internet transition mechanism for Internet IPv4 to IPv6 migration. 6in4 uses tunnelling to encapsulate IPv6 traffic
over explicitly-configured IPv4 links. As defined in RFC 4213, the 6in4 traffic is sent over the IPv4 Internet inside IPv4 packets
whose IP headers have the IP protocol number set to 41. This protocol number is specifically designated for IPv6
encapsulation.

In the diagram above, the 6in4 usually needs to register to a 6in4 tunnel service, known as a Tunnel Broker. It also needs the
end point global IPv4 address 114.39.16.49 to complete the 6in4 setting.
