The IESG has received a request from the IPv6 Operations WG (v6ops) to consider the following document: - 'Recommendations for Discovering IPv6 Prefix Used for IPv6 Address Synthesis' <draft-ietf-v6ops-prefer8781-04.txt> as Informational RFC
The IESG plans to make a decision in the next few weeks, and solicits final comments on this action. Please send substantive comments to the [email protected] mailing lists by 2025-07-28. Exceptionally, comments may be sent to [email protected] instead. In either case, please retain the beginning of the Subject line to allow automated sorting. Abstract On networks providing IPv4-IPv6 translation (RFC7915), hosts and other endpoints might need to know the IPv6 prefix(es) used for translation (the NAT64 prefix). While "Discovery of the IPv6 Prefix Used for IPv6 Address Synthesis" (RFC7050) defines a DNS64-based prefix discovery mechanism, more robust methods have been developed since then. This document provides guidelines for NAT64 prefix discovery, recommending more deterministic alternatives like obtaining the NAT64 prefix from Router Advertisement option (RFC8781) over RFC7050 when available. The file can be obtained via https://datatracker.ietf.org/doc/draft-ietf-v6ops-prefer8781/ No IPR declarations have been submitted directly on this I-D. _______________________________________________ IETF-Announce mailing list -- [email protected] To unsubscribe send an email to [email protected]
