Even if this reflects the original intent of ASNs, it certainly does not fit current reality. Let's call any set of networks under a unified administrative control an Autonomous Routing Domain (ARD). ARDs should not be confused with ASes (an implementation detail). They are distinct for these reasons: 1) Most ARDs do not have an ASN -- they are statically routed "at the edge". 2) Many networks "at the edge" use private ASNs. 3) Many ARDs share a provider provided ASN -- RFC 2270. 4) Many ARDs are implemented with multiple ASNs. Internap is probably an extreme example. But even UUNet's global ARD (AS701, 702, 705 ...) reflects an implementation choice (one that Sprint does not seem to follow with 1239, for example). ---tim
