I suspect creating a new term for the root name servers is unlikely to be helpful to anyone.

What's a "VGNIC"?  I presume it is not the Network Information Center for the British Virgin Island (a la JPNIC, CNNIC, KRNIC, TWNIC, etc).

A graphical representation of root name server instance distribution can be found at:


(Note that the location of the "B" root name server instance is not in the South Atlantic just off the coast of western Africa (Lat: 0, Lon: 0), but in Los Angeles, US).

It might also be useful to observe that a common technique at larger ISPs and other resolver operators is to mirror the root zone into their resolvers, thereby removing the need of those resolvers to actually query the root servers.  As such, those resolvers could be considered to be a form of root name servers as well. Of course, it is a bit challenging to identify which resolvers actually do this mirroring...
