I'd say it's not meaningful, as when the refid is a "name" it's one
of the refclock names (GPS, MSF, PPS etc).
If the refid is an IPv4 address you could do a PTR lookup, then an
A lookup on the resulting name as a cross check. That appears to be
what the xntp version of ntpq -p does, but not explicitly; I think
the A lookup is done internally by some library routine.
