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.
