Paul, We agree on all but this small point. Certainly one should allocate ip address space in a topological manner. However, I know of several large NSP/ISPs that don't because there's no [technological or economic] punitive incentive for them to do so. I believe that the correlation between topology and geography will increase as a function of time. In fact, I believe that today the correlation is quite high. The lack of correlation is the exception, in my experience, than the rule. -alan Quoting Paul Ferguson (ferguson@cisco.com):

Accordingly, not allocating in a geographic fashion lends to deaggregation, which is bad.
Correction: Not allocating in a topological fashion lends to deaggregation. Geography often has nothing to do with it.
