Why is it excluded? It's too easy for people to make up reasons why they shouldn't have to think, or heaven forbid, renumber. I'd wager a pound of reese's pieces that Sean threw those paragraphs out of his mind, with less than an hour's thought.

As for the reordering crisis, order the book from the Phonics people, it might help -> D-H-C-P. What? Your software doesn't support it? Erm, call your sales rep. Make threats; threaten to go to Microsoft who does. These things can be done, and the current state of the net can be much eased by providers enforcing prefix aggregation impetus. It could also be done by being "good net.citizens" and all that ruckus, but the masses don't move unless forced to. Somone needs to force them. Thank you, Sprint, for slowing the acceleration with your /19 policy. Now, let's see if we can't decrease the problem with historical prefix aggregation rules, or retirement so as to achieve the same effect. -alan
