To the outside world, all published name servers are equally "authoritative".
The master/slave (or "primary / secondary") relationship only matters for
distribution of zone content between those servers.
I'm probably going to get myself in trouble for ignorance, but if my
CPE's dns is not listed as an NS from the root servers, I don't think it's
authoritative. It may be supplying the zone via some master/slave
arrangement with the ISP, but that's only how the ISP getting its brains
for the home zone, and is just using zone transfers to affect that.
Sorry if this is a rathole.
