Methods, apparatus, and software for accessing location based Internet services by automatically populating DNS tables with subscriber location information. The DNS tables are updated responsive to information provided on subscriber call set-up. The location may be derived directly for the content of the call set-up, or may be derived in conjunction with one or more pre-existing databases. Ideally the DNS entry is a mapping from IP address (or subnet address) to location, though a mapping from domain name to location will also be effective. When a location based service is requested by a subscriber, the requested service may interrogate the DNS table to retrieve the requesting user's location without requiring further subscriber intervention.
