Technologies are generally described for a systems, methods and devices for implementing device and session identification. In some examples, a processor may receive a first communication from a device. The first communication may include requests to interact with a web page, a session identifier associated with the first communication, and a protocol address associated with the device. The processor may receive a second communication from the device. The second communication may include a device identifier associated with the device, where the device identifier may be different from the internet protocol address, and the session identifier. The processor may link the first communication with the device identifier based on the session identifier. The processor may further analyze the first communication with respect to the device identifier to produce an analyzed first communication.
