Dear DNSOP, John and I have made a number of changes since the start of Working Group Last Call, thanks to your good feedback. Here's a summary of the noteworthy changes since -06:
- The abstract emphasizes this document speak to operational requirements, in alignment with previously documented implementation requirements. - Noted that this document updates RFC 1123 - Background section has been renamed to History of DNS over TCP - Updated and clarified text on connection termination - An earlier version mistakenly assumed that OpenBSD had the TCP "accept filter" feature - EDNS(0) everywhere, instead of just EDNS - Have added a few new or missing references to BIND, ECDSA, flag day 2020, and the KSK rollover list archives. - Numerous updates to RFC references, including newly published RFCs and cases where some RFCs have new revisions published. Also a number of RFC references were moved to the Normative section. - Numerous other grammatical and typographical fixes DW > On Jun 8, 2021, at 4:10 PM, internet-dra...@ietf.org wrote: > > A New Internet-Draft is available from the on-line Internet-Drafts > directories. > This draft is a work item of the Domain Name System Operations WG of the IETF. > > Title : DNS Transport over TCP - Operational Requirements > Authors : John Kristoff > Duane Wessels > Filename : draft-ietf-dnsop-dns-tcp-requirements-10.txt > Pages : 29 > Date : 2021-06-08 > > Abstract: > This document updates [RFC1123].
