Adobe has partnered with Digital Envoy, a leading provider of IP intelligence and authentication solutions, to offer GeoSegmentation, a geographical measurement capability based on end users' IP addresses. While accuracy based on individual data sets may vary, generally Digital Envoy offers over 99% accuracy at the country level, over 97% accuracy at the region level, and over 90% accuracy at the city level.
Some factors which may influence GeoSegmentation data include:
- IP addresses that represent corporate proxies. These can appear as traffic coming through the user's corporate network, which may actually be a different location if the user is working remotely.
- Mobile IP addresses. Mobile IP targeting works at varying levels depending on the location and the network. A number of carriers backhaul IP traffic through centralized or regional POPs.
- IP addresses belonging to users of satellite ISPs. Identifying the specific location of these users is difficult, as they usually appear to come from the location of the uplink.
- Military and government IPs. This often represents personnel traveling around the globe and entering through their home location, rather than the base or office where they are currently stationed.
