Since they are neutral exchanges, w/o policy, I can only speak for for my project. I can't speak for any of the other sites that are attached. The RA has active peering sessions at all the NAPS. We do not have active peering sessions with some of the NSP's which are receiving NSF funding through the old regionals. What is your definition of used? > >> .

That question can't be answered by the NAP operators, since they don't monitor traffic.

Anywhere to WELL.COM (via the PB NAP) Anywhere to NAP.NET (via the AADS NAP) Anywhere to CERF.NET (via the Sprint NAP) Of course your query presumes symetric routing, which is the exception rather than the rule these days. > >> .

You can dump the in-addr zones to discover who has been assigned an IP address You can see who has signed an MPLA, if they exist. You can check the CERFnet MAP You can check out http://info.ra.net/div7/ra/ep.html All of these have different viewpoints on the "NAP-union" and none have what I think you want. --bill
