However, there are a few reasons why we, even though IPv6 does not solve the problem, _can_ solve it: 1) organizations, however large, can be represented by one "dot", a /48. This enables us, at worst, to have O(organizations) routing table entries, not O(organizations * average number of nodes per organization). The former is too big still, but it is still good news and makes aggregation and address space estimations easier. 2) it's all new protocol -- not a win as such, but due to this, we can _reinvent_ the routing system (within some restrictions) the way we see fit, based on earlier experience. Let's not pretend 2) does not exist. There are 6bone routing guidelines, which have been happily adapted by production operators (sTLA) also; they prevent most of the problems we're now facing with IPv4 global routing table growth. Why toss all of that aboard, pretending we cannot work around the routing problem for now when moving to IPv6 (note: I didn't say IPv6 would magically solve the problem!)? -- Pekka Savola "Tell me of difficulties surmounted, Netcore Oy not those you stumble over and fall" Systems.
