Network World has a 2 part in depth article about the infrastructure of the Internet as a sort of "health" report in Sep 16 issue (part 1). Many people in NANOG quoted. Not a bad article except for ... "Carriers are beginning to mandate use of Complex Inter Domain Routing address blocks, which are analogous to area codes..." Those that have an acct on www.nwfusion.com can find it at #9603. Hank
