Abstract While the Domain Name System (DNS) [2,3] is generally used to store predefined types of information (e.g., addresses of hosts), it is possible to use it to store information that has not been previously classified. This paper describes a simple means to associate arbitrary string information (ASCII text) with attributes that have not been defined by the DNS. It uses DNS TXT resource records to store the information. It requires no change to current DNS implementations.
