The Knowbot Information Service (KIS), also known as netaddress, is an Internet user search engine that debuted in December 1989.
It provided a uniform user interface to a variety of remote directory services such as whois, finger, X.500, and MCI Mail.
By submitting a single query to KIS, a user can search a set of remote white pages services and see the results of the search in a uniform format.
There are several interfaces to the KIS service including e-mail and telnet.
KIS consists of two distinct types of modules that interact with each other (typically across a network) to provide the service.
