The Future of IP Address as a Measurement Signal
Evan Cohen from CIMM introduced Greg Galletta from Truthset, who described a study that they had recently completed, which rigorously evaluated the accuracy of IP addresses as an identity and measurement signal. The study compared six major data providers’ full IP–to–identity graphs against “true sets” from two large ISPs and one MVPD over a 90-day period. The study analyzed roughly 900 million IP→postal and IP→email linkages against ~1.5 million validation records. Researchers checked the validation samples for geographic and distributional bias and replicated all calculations with an independent second party to confirm robustness.
