Abstract
Digital products are delivered to a client computer through a wide area network such as the Internet only upon determination that the client computer is located in a geopolitical territory, such as a country or state, for which delivery of the digital product is authorized. A server computer estimates the geopolitical location of the client computer from the client computer'"'"'s network address through contact information in a network address allocation database. Alternatively, the server computer estimates the geopolitical location of the client computer from the client computer'"'"'s custom name, e.g., domain name. The domain name itself can specify a country within which the client computer is located. Such can be conventional or can be parse according to ad hoc patterns developed by large, international organizations identified by a root domain name. In addition, contact information for the domain name can be retrieved and geopolitical territory information parsed from the contact information. A super-classification of the domain name can indicate a geopolitical territory. Records associating geopolitical territories with network address ranges are stored in such a manner that maximizes resolution within a cache of such records, perhaps at the expense of reduce efficiency but so as to maximum currency and accuracy.

25. A system for permitting access to a digital product by a client computer, comprising:
-
means for receiving a request to access the digital product;
means for determining that a restriction limits availability of the digital product to at least one allowed territory;
means for determining a client computer location by;
accessing at least one allocation database associated with a client computer network address to obtain allocation record data;
parsing the allocation record data for location information; and
setting the location information as the location of the client computer within a geographical territory; and
means for permitting access to the digital product by the client computer conditioned upon the geographical territory being one of the allowed territories. - View Dependent Claims (26, 27, 28, 29, 30, 31, 32, 33)
