From what I understand at least RIPE NCC is using the meaning along the
lines of "A network with the same administrative domain confined to a
single or a group of buildings".

As such a site could be (amongst others):
 - a host in a datacenter which provides VPN's to other sites
   over its own link.
 - a home network, eg where a DSL or cable line or a PPP link terminates
 - an office in a home network where a VPN/PPP/DSL terminates
 - a big office complex, where the network is run by an admin group
   who have an incoming 1Gbit/s link
 - multiple buildings around a city/country/world all linked
   together with VPN using one single /48, but eg a /56 per building.

And various other cases. Note that I add the way the network gets
connected to the rest of the world. Of course there are cases where one
does not link up to the Internet or even to other sites.

I am pretty sure that the various RIR's are well known enough with a
definition that they handle consistently in their region, which in one
way or the other most likely matches the above.

Maybe somebody should write a mini-RFC labeled "What is a site" and
include some examples to show exactly how/what? Guess it would fit in
perfectly for the v6ops WG (cross cc'd for that purpose).

Greets,
 Jeroen
