I like the MAC-style format too. Even without IPv6 we have the ambiguity associated with reference clocks
e.g.
Reference ID : 83.79.67.75 (SOCK)
Maybe for chrony 2.5 (I think its probably too late for 2.4) the chronyc tracking display should carry a warning that the first field is not an IP address and that the format will change in the future. The change could then be made in chrony 2.6.
