Internet Engineering Task Force (IETF) C. Bao Request for Comments: 6052 CERNET Center/Tsinghua University Updates: 4291 C. Huitema Category: Standards Track Microsoft Corporation ISSN: 2070-1721 M. Bagnulo UC3M M. Boucadair France Telecom X. Li CERNET Center/Tsinghua University October 2010 IPv6 Addressing of IPv4/IPv6 Translators Abstract This document discusses the algorithmic translation of an IPv6 address to a corresponding IPv4 address, and vice versa, using only statically configured information. It defines a well-known prefix for use in algorithmic translations, while allowing organizations to also use network-specific prefixes when appropriate. Algorithmic translation is used in IPv4/IPv6 translators, as well as other types of proxies and gateways (e.g., for DNS) used in IPv4/IPv6 scenarios. Status of This Memo This is an Internet Standards Track document. This document is a product of the Internet Engineering Task Force (IETF). It represents the consensus of the IETF community. It has received public review and has been approved for publication by the Internet Engineering Steering Group (IESG). Further information on Internet Standards is available in Section 2 of RFC 5741.
