Abstract
An identification service may provide a device identifier that is available in both browser and non-browser applications on an electronic device. The identification service may include a domain name system server that handles domain name system queries for certain HTTP requests originating from the browser and non-browser applications. An HTTP request in the non-browser application may result in the domain name system server embedding the device identifier into an IPv6 address that is then stored in a local domain name system cache on the device. An HTTP request in the browser application may cause the browser to connect to the IPv6 address stored in the local domain name system cache. The identification service may have an HTTP server bound to the IPv6 address. The HTTP server may extract the device identifier from the IPv6 address and may provide the device identifier to the browser application.
