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
   and RFC5936 with respect to efficient use of TCP connections, and
   RFC7766 with respect to the recommended number of connections between
   a client and server for each transport.
