Abstract

The Stateless IP/ICMP Translation Algorithm (SIIT) [RFC6145] specifies that when translating IPv4 addresses to IPv6 and vice versa, all addresses must be translated using the algorithm specified in [RFC6052]. This document specifies an alternative to the algorithm specified in [RFC6052], where IP addresses are translated according to a table of Explicit Address Mappings configured on the stateless translator. This removes the previous constraint that IPv6 nodes that communicate with IPv4 nodes through SIIT must be configured with IPv4-translatable IPv6 addresses.

       Explicit Address Mappings for Stateless IP/ICMP Translation

Abstract

   This document extends the Stateless IP/ICMP Translation Algorithm    (SIIT) with an Explicit Address Mapping (EAM) algorithm and formally    updates RFC 6145.  The EAM algorithm facilitates stateless IP/ICMP    translation between arbitrary (non-IPv4-translatable) IPv6 endpoints    and IPv4.
