IMHO, YMMV, of course.
The sentence is updated in 2 ways - changing SHOULD to MUST and - the reference to using TCP just for zone transfers is also removed which might be why it seemed easier to just restate it in RFC5966. Would it help if Section 5 was updated to read: “ Section 6.1.3.2 of [RFC1123] is updated: All general-purpose DNS implementations MUST support both UDP and TCP transport.” > > Adding the "Updates: 1035, 1123" is necessary, though. Agreed, will update. Regards Sara. _______________________________________________ Gen-art mailing list [email protected] https://www.ietf.org/mailman/listinfo/gen-art
