A site which doesn't renumber will need to have his more specific route propogated to the far corners of the Internet. 1) Anyone care to estimate how much this route costs to the combined set of multiply-connected providers and sites? (Need to include router memory, forced introduction of new routers, update bandwidth, etc. for every affected network...) 2) Given the answer to #1, is there some way to recover these costs? /John p.s.
