The IESG has approved the following document: - 'Operational Guidelines for DNS Transport in Mixed IPv4/IPv6 Environments' (draft-ietf-dnsop-3901bis-17.txt) as Best Current Practice
This document is the product of the Domain Name System Operations Working Group. The IESG contact persons are Mahesh Jethanandani and Mohamed Boucadair. A URL of this Internet-Draft is: https://datatracker.ietf.org/doc/draft-ietf-dnsop-3901bis/ Technical Summary This document provides guidelines and documents Best Current Practice for operating authoritative DNS servers as well as recursive and stub DNS resolvers, given that queries and responses are carried in a mixed environment of IPv4 and IPv6 networks. This document recommends that authoritative DNS servers as well as recursive DNS resolvers support both IPv4 and IPv6. It furthermore provides guidance for how recursive DNS resolvers should select upstream DNS servers, if both native and IPv4-embedded IPv6 addresses are available. This document obsoletes RFC 3901. Working Group Summary The WG consensus is strong. There was discussion, not controversial, about avoiding fragmentation by using an encrypted DNS protocol, but it was resolved in a way that all parties in the discussion agreed with. Document Quality This is a Best Current Practice document that provides guidance on the IPv6/IPv4 deployment on the usage of mixed IP in the DNS deployments. Personnel The Document Shepherd for this document is Ondřej Surý. The Responsible Area Director is Mohamed Boucadair. _______________________________________________ DNSOP mailing list -- [email protected] To unsubscribe send an email to [email protected]
