.SH DESCRIPTION
.B whois
searches for an object in a
.I RFC-812
database.

This version of the whois client tries to guess the right server to
ask for the specified object. If no guess can be made it will connect
to whois.internic.net for domains, whois.arin.net for IPv4 addresses
and whois.6bone.net for IPv6 addresses.

.SH HISTORY
This program closely tracks the user interface of the whois client
developed at RIPE by Ambrose Magee and others on the base of the
original BSD client.
I also added support for the protocol extensions developed by David
Kessens of QWest for the 6bone server.
