We have to make routing scale, and that demands aggregation, which in turn demands structured addresses. Look at it this way. We have about 75K routes in the "default-free zone" now. If we just assigned addresses sequentially, we'd need a route for every endpoint. There are what, 100,000,000 nodes today, and more tomorrow? We can't handle 3 orders of magnitude increase in the size of that table, let alone what it will be in a few years. There are lots of other practical issues, but that's the big one. --Steve Bellovin
