Abstract
A Domain Name System (DNS) proxy agent of the present invention performs a name query relaying function by redirecting DNS queries and responses to their final destination address, which is unknown to the node which originated the query or response. The real source and destination nodes are known only to the DNS proxy agent. This allows network address of an Internet-based name server to be changed without the requirement to reconfigure the DNS addressed on the LAN-based host.
