Hi All, This update hopefully addresses the two DISCUSS positions raised in the IESG review, and also all the comments made there. The main changes are: * Add section 8.1 on the requirement to use the DoT ALPN * Modify one of the options for validation of a client from just an IP ACL to a combination of IP ACL and TSIG/SIG(0) * Update Abstract and Introduction with clear descriptions of how earlier specifications are updated * Add reference for NSEC3 attacks * Justify use of SHOULD in sections 7.3.2 and 7.3.3. * Clarify the Appendix is non-normative * Numerous typos and editorial improvements. * Use xml2rfc v3 (some format changes occur as a result) Best regards Sara. > On 27 May 2021, at 09:32, internet-drafts@ietf.org wrote: > > > A New Internet-Draft is available from the on-line Internet-Drafts directories. > This draft is a work item of the DNS PRIVate Exchange WG of the IETF. > > Title : DNS Zone Transfer-over-TLS > Authors : Willem Toorop > Sara Dickinson > Shivan Sahib > Pallavi Aras > Allison Mankin > Filename : draft-ietf-dprive-xfr-over-tls-12.txt > Pages : 42 > Date : 2021-05-27 > > Abstract: > DNS zone transfers are transmitted in clear text, which gives > attackers the opportunity to collect the content of a zone by > eavesdropping on network connections.
