"because of the way tcp/ip works..." is a very good lead-in toward the actual cause of this apparent non-caring / laziness. because of the way ip works, and because of the way human nature works, many of the things that would have to be done to fix this problem have assymetric cost/benefit. if a network provider isn't lazy, then everyone except them will benefit from that non-laziness. human nature says that ain't happening. even though i try every day, it probably is too late to redesign human nature. the assymetric cost/benefit is an emergency property of fundamental design principles in tcp/ip, so it's no surprise that ipv6 didn't do much about this "weakness". attempting to symmetrize cost/benefit without design changes in either human nature or the tcp/ip protocol suite has had mixed results. (i.e., MAPS.) so, the article sean quoted is all very entertaining, but says nothing new, which is sad, because i for one would really like to hear something new. -- Paul Vixie
