Abstract

A system (300) prefetches most frequently used domain names and stores the domain name data (320) at local cache servers (310), It generates validity codes (330) to enable error checking for valid domain names at the local cache servers (310) without accessing root servers (130). A cache server (310) obtains, stores, and propagates updated or new DNS data to local cache servers (340) at predetermined intervals. Users can obtain Internet protocol addresses of domain names directly from local cache servers (310), thus eliminating processing delays over the Internet.
