Abstract: A network address server is configured to resolve a target network address name label with a network address, with the target address name label defining a branch of one level of a multi-level network address name space. The network address server is one of a plurality of network address servers each being uniquely associated with a respective region of the address name space level. The network server includes an address name database, and an address name processor in communication with the address name database for providing a response to a query for the network address corresponding to the target address name label. The address name database includes a number of database records, each identifying a unique address name label and a network address uniquely associated with the address name label.
