1. 6in4

   6in4 is an IPv6 transition mechanism for migrating from Internet Protocol version 4 (IPv4) to IPv6. It is a tunneling protocol that encapsulates IPv6 packets on specially configured IPv4 links according to the specifications of RFC 4213. The IP protocol number for 6in4 is 41, per IANA reservation.The 6in4 packet format consists of the IPv6 packet preceded by an IPv4 packet header. Thus, the encapsulation overhead is the size of the IPv4 header of 20 bytes. On Ethernet with a maximum transmission unit (MTU) of 1500 bytes, IPv6 packets of 1480 bytes may therefore be transmitted without fragmentation. 6in4 tunneling is also referred to as proto-41 static because the endpoints are configured statically. Although 6in4 tunnels are generally manually configured, the utility AICCU can configure tunnel parameters automatically after retrieving information from a Tunnel Information and Control Protocol (TIC) server. The similarly named methods 6to4 or 6over4 describe a different mechanism. The 6to4 method also makes use of proto-41, but the endpoint IPv4 address information is derived from the IPv6 addresses within the IPv6 packet header, instead of from static configuration of the endpoints.

1. 6in4

   6in4 is an Internet transition mechanism for migrating from Internet Protocol version 4 to IPv6. 6in4 uses tunneling 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 6in4, the IPv4 packet header is immediately followed by the IPv6 packet being carried. This means that the encapsulation overhead is simply the size of the IPv4 header of 20 bytes. With an Ethernet Maximum Transmission Unit of 1500 bytes, one can thus send IPv6 packets of 1480 bytes without fragmentation. 6in4 tunneling is also referred to as proto-41 static because the endpoints are configured statically. Although 6in4 tunnels are generally manually configured, for example the utility AICCU can configure tunnel parameters automatically after retrieving information from a Tunnel Information and Control Protocol server. There are similarly named methods, namely 6to4 or 6over4, which describe a different mechanism. The method 6to4 makes use of proto-41 too, but instead of static configuration of the endpoints, the endpoint IPv4 address information is derived from the IPv6 addresses within the IPv6 packet header.
