A method and system for domain name resolution in a communications network including the steps of intercepting communication to and from the network and replacing DNS primary and DNS secondary IP address by an interceptor program. The interceptor program copies then replaces the IP addresses in messages received from the network to a spoof address so that an alternate application will receive the domain name resolution requests. The interceptor program replaces the IP addresses in messages sent to the network from the spoof address to the copied addresses. The alternate application receives the domain name resolution request and replaces the IP address of the request which is the spoof address to the copied IP addresses. The alternate application sends the domain name resolution requests to the copied IP addresses operatively simultaneously.

Method and system for domain name resolution in a communications system

Methods and systems consistent with the present invention provide broadband subscribers with dynamic, automatic routing information for accessing services offered by a service provider network () and/or content provider networks (). Client software on the subscriber's computer () retrieves a file such as an HyperText Markup Language (HTML) document from a predetermined server containing connection-oriented routing information for gaining access to various network services. The client software parses the HTML document and extracts the routing information. The client software then uses this routing information to populate and manipulate the subscriber computer () routing table.

Dynamic file-based routing in a broadband communications system

In one aspect of the invention a method includes, at a tunneling server, receiving from first client a point-to-point protocol signal encapsulated within a network address request header, the point-to-point protocol signal comprising an identifier identifying a destination client. The method further comprises encapsulating the point-to-point signal within a network address response header and communicating the network address response encapsulated signal toward the destination client.
