SIIT: RFC 2765
Line 6:
In [[Computer_network|computer networking]], '''Stateless IP/ICMP Translation''' 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]] and is described in [[Request_for_Comments|RFC]] 2765 ([[Network Working Group]] at [[Internet_Engineering_Task_Force|Internet Engineering Task Force]]).
 
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|IPv4 address]] to an [[IP_address|IPv6 address]] or vice-versa may vary, and the means by which the routing occurs is described as unspecified in the RFC.
