More modern ntpd with the Command Line Option -I,
and / or the MiscOpt nic / interface configuration directive,
could probably get the MAC address of the interface it using,
(or some other uniqueish id) hash it, ...
ntpd\ntp_io.c link interface into list of known interfaces
ep_univ_iid; /* iface ID from MAC address */
scan_univ_iid; /* see RFC 4291 */
ep_privacy; /* random local iface ID */
scan_privacy; /* see RFC 4941 */
I don't know where you'd stick the data,
perhaps in an extension field.
Similar to the ipv4 ref clock id lack of resolution issue,
when IPv6 is the source?
