HTTP lets devices take advantage of the extensive server-side infrastructure already in place for wired networks. Furthermore, because no unrequested HTTP packets can arrive at the device, implementing the networking interface is easier.

Supporting the HTTP protocol does not imply that the device must support a particular Internet Protocol (IP).
