Serious question: What about EarthLink's non-EarthLink-owned modems? (They
do lease some modems, I have dialed into one before. :) And what about
NetZero-type companies that outsource all of their modems?
If he is measuring traffic off routers, I do not see how he could
differentiate between traffic on modem leased by $PROVIDER_A and traffic on
that same modem an hour later leased by $PROVIDER_B.
Also, does he, or anyone else, have any explanation why [insert favorite
obvious big backbone] is missing from that list? I know most of the ASes I
used to see as "big" are not listed.
