Line 3: == Stateless IP/ICMP Translation (SIIT) == RFC 2765 defines a mechanism known as ''Stateless IP/ICMP Translation'', or '''SIIT'''. SIIT is a mechanism which translates [[IPv6]] packets into [[IPv4]] packets and vice-versa. It was initially drafted in February of 2000 by E. Nordmark of [[Sun Microsystems]]. Basically SIIT describes a method by which a [[router]] interprets an [[IPv4#Header\|IPv4 header]] and creates a parallel [[IPv6#IPv6_packet\|IPv6 header]] with equivalent information and the inverse equivalent operation of converting an [[IPv6#IPv6_packet\|IPv6 header]] into an [[IPv4#Header\|IPv4 header]]. The actual means of converting an [[~~IP_address~~IP address\|IPv4 address]] to an [[~~IP_address~~IP address\|IPv6 address]] or vice-versa may vary, and the means by which the routing occurs is described as unspecified in the RFC. Due to the method in which SIIT operates it is not a sufficient migration mechanism in that it is incapable of coordinating more than two unique addresses on either side. This means that every IPv6 host would be required to have a globally routable IPv4 address as well.
