Abstract
The present invention provides for a Domain Name Router (DNR) that uses domain names to route data sent to a destination on a network (e.g., a stub network). Each corporate entity or stub network can be assigned one or a small number of global addresses. Each of the hosts on the stub network can be assigned a local address. When a source entity sends data to a destination entity with a local address, the data is sent to the DNR using a global address. The source entity embeds the destination's domain name and its own domain name inside the data. The DNR extracts the destination's domain name from the data, translates that domain name to a local address and sends the data to the destination.
