Abstract
A device may receive a first request to determine a public-facing Internet Protocol (IP) address of a mobile device. The device may transmit, in response to the first request, and to the mobile device, the public-facing IP address. The device may receive a second request, from the mobile device, to authenticate the mobile device to receive downloadable content, the second request including the public-facing IP address of the mobile device. The device may receive a third request, from the mobile device, for a license to receive a particular content item and determine whether the public-facing IP address, corresponding to the mobile device, is valid for the particular content item. The device may transmit the license to the mobile device when the public-facing IP address is determined to be valid for the particular content item, where the license includes decryption keys for the particular content item.
