Verizon, Sprint Carried More 3G Traffic Than AT&T In '09 > What methods were used to measure?

said by omonymous :

99% of the time, my at&t connection was incorrectly identified as a Verizon connection. It is always wrong on the dslreports homepage and usually wrong on any site that tries to guess my carrier.

How did these guys calculate traffic for each carrier?

said by EasyaCaveMan :

This one is easy if one uses common sense. Typically each provider is given a range if IP addresses which are assigned to them. Then they assign that IP address to your phone when your in 3g mode.

Either 2 things are wrong here.... DSL reports data is incorrect on what ISP has what range if IP address's, or your somehow viewing this page by using a mobile device that is connected to your wifi hotspot that just happens to be verizon DSL...

If thats not the case, then the first one is most logical. Just like number porting, each company is assigned a bank of numbers and could start out at sprint, move to t-mobile, then to Verizon and then to ATT, but the minute you cancel, that number goes right back to Sprint...
