Abstract
One embodiment of the present invention provides a system for looking up location-specific configuration information for a network node or a subnet. During system operation, a network node creates a query message containing a key that comprises an Internet Protocol (IP) prefix and a string, wherein the IP prefix identifies the network node or the subnet, and the string specifies the type of configuration information. The network node then sends the query message to a name server, which is part of a distributed system that provides a global naming service, wherein the name server additionally stores configuration information. Finally, the network node receives a response message from the name server, wherein the response message contains the requested configuration information.
