Can I clarify:
This 'multicast' is not necessarily the same as the IANA addresses, and FF0X::101. says:
The NTP multicast address assigned by the IANA should NOT be
used, unless specific means are taken to avoid spraying large areas of the
Internet with these messages
does not have this section, of course.

On my IPv6-enabled server, the ntpsec by default does not seem to be
listening to , and ::101
