Moin, after the discussion at 123, I just uploaded a new version of draft- ietf-dnsop-3901bis;
As discussed at the meeting, I would like to ask all of you to thoroughly read it and provide feedback on the text and document overall. The repository for issues/PRs is here: https://github.com/ietf-wg-dnsop/draft-ietf-dnsop-3901bis/ This version has the following changes: - Added text on the issues of synthesized v6 addresses, if non-synthesized addresses are available - Added text clarifying that resolvers SHOULD also prefer non-synthesized v6 over synthesized v6 when communicating with upstream DNS servers (same as stub) - Increased guidance on zone testing (test for EDNS1232, TCP support, MTU breakage resillience, actual resolvability in addition to just v4/v6 record presence) With best regards, Tobias On Mon, 2025-07-28 at 02:12 -0700, [email protected] wrote: > A new version of Internet-Draft draft-ietf-dnsop-3901bis-03.txt has > been > successfully submitted by Momoka Yamamoto and posted to the > IETF repository. > > Name: draft-ietf-dnsop-3901bis > Revision: 03 > Title: DNS IPv6 Transport Operational Guidelines > Date: 2025-07-28 > Group: dnsop > Pages: 13 > URL: > https://www.ietf.org/archive/id/draft-ietf-dnsop-3901bis-03.txt > Status: https://datatracker.ietf.org/doc/draft-ietf-dnsop-3901bis/ > HTML: > https://www.ietf.org/archive/id/draft-ietf-dnsop-3901bis-03.html > HTMLized: > https://datatracker.ietf.org/doc/html/draft-ietf-dnsop-3901bis > Diff: > https://author-tools.ietf.org/iddiff?url2=draft-ietf-dnsop-3901bis-03 > > Abstract: > > This memo 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.
