The IESG has received a request from the DNS PRIVate Exchange WG (dprive) to
consider the following document: - 'DNS Zone Transfer-over-TLS'
  <draft-ietf-dprive-xfr-over-tls-09.txt> as Proposed Standard

The IESG plans to make a decision in the next few weeks, and solicits final
comments on this action. Please send substantive comments to the
last-call@ietf.org mailing lists by 2021-04-20. Exceptionally, comments may
be sent to iesg@ietf.org instead. In either case, please retain the beginning
of the Subject line to allow automated sorting.

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.  The DNS Transaction Signature
   (TSIG) mechanism is specified to restrict direct zone transfer to
   authorized clients only, but it does not add confidentiality.  This
   document specifies the use of TLS, rather than clear text, to prevent
   zone content collection via passive monitoring of zone transfers:
   XFR-over-TLS (XoT).  Additionally, this specification updates
   RFC1995, RFC5936 and RFC7766.
