Abstract: Peer-to peer licensing tracking and control is disclosed. In one embodiment, a method may include individually disabling a controller module when a code to activate the controller module is different from a number embedded in the controller module, and automatically disabling the controller module when the number is associated with another controller module communicatively coupled to the controller module. The method may further include a master controller module periodically querying one or more of controller modules communicatively coupled to the master controller module. The querying may identify the number and the feature associated with each of the controller modules to store in a validation module of the master controller module as a database. When the number of the controller module matches with one or more numbers of the controller modules listed in the database, the controller may be deactivated.
