I asked on a DNS directorate + wg chairs sync earlier today and nobody
seemed to have in mind either (a) a single good reference nor (b) a
single good definition for a "geofenced name".

Perhaps we can begin by clarifying what it means to you?  In mind
there were two alternatives; roughly:

    [a] a name for which a DNS authoritative will hand out different
RRs depending on the client src IP (conceptual proxy for geolocation),
or

    [b] a name for which a DNS authoritative will either hand out some
RRs **or** return NODATA or some kind of error to others, as a
function of client IP.

Are either of those close to what you mean?
