Abstract

A DNS server system provides IP addresses for a host in a computer network. Upon receiving a request from a client for an IP address associated with a domain name, the requested IP address is retrieved from an object oriented database and transmitted to the client. The DNS server system provides configuration access from a client in a computer network. Communicative coupling is established between a client web browser and a DNS server system web server. A user interface adapted to provide configuration access to a DNS server system is requested. The user interface is downloaded from the DNS server system over the computer network.
