Folks,

We have published a rev of our I-D on NTP port randomization, based on
the feedback we've received so far:
https://www.ietf.org/internet-drafts/draft-gont-ntp-port-randomization-01.txt

At this point we'd like the wg to consider our document for wg adoption.

Thanks!

Cheers,
Guillermo & Fernando

Abstract:
   The Network Time Protocol can operate in several modes.  Some of
   these modes are based on the receipt of unsolicited packets, and
   therefore require the use of a service/well-known port as the local
   port number.  However, in the case of NTP modes where the use of a
   service/well-known port is not required, employing such well-known/
   service port unnecessarily increases the ability of attackers to
   perform blind/off-path attacks, since knowledge of such port number
   is typically required for such attacks.  This document formally
   updates RFC5905, recommending the use of port randomization for those
   modes where use of the NTP service port is not required.




Please note that it may take a couple of minutes from the time of submission
until the htmlized version and diff are available at tools.ietf.org.
