Abstract: A distributed address database management technique involves maintaining an address database by each of a number of interconnected modules. Each module maintains a number of locally owned address entries and a number of remotely owned address entries in the address database. Each module monitors the status of its locally owned address entries, maintains the locally owned address entries based upon the status, and provides the status to the other interconnected modules. Each module maintains the remotely owned address entries based upon the status received from the other interconnected modules. When a module adds a locally owned address entry to its address database, the module notifies the other interconnected modules, which in turn add a corresponding remotely owned address entry to their respective address databases.

Abstract: A technique for domain name resolution in a communication network having multiple overlapping address domains involves translating a destination host domain name into a destination host local address that is ambiguous within the communication network, and then translating the destination host local address into a unique destination host global address. A domain name system proxy uses a domain name system server in the destination address domain to translate the destination host domain name into the destination host local address, and uses a network address translator to translate the destination host local address into the destination host global address.
