Abstract
In one aspect, a method of IP obfuscation of a user device includes receiving, over an Extendible Authentication Protocol (EAP) session between a user device and a network access point, location preferences of the user device, generating, based on the location preferences or a network policy, a geohash for the user device, identifying, for the user device, an IP anchor, sending, over the EAP session, the geohash to the user device, and receiving, from the user device, network traffic, wherein the network access point utilizes the geohash and the IP anchor to route the network traffic for the user device and obfuscate IP address of the user device from third-party access.
