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.  This document formally updates
    RFC5905, recommending the use of port randomization for those modes
    where use of the NTP service port is not required.
