about your rwhois howto (http://www.unixadmin.cc/rwhois/rwhois-ip-howto.html)

[Jeff Neuffer Jr]

Anton,

You should be able to connect to the Rwhois server and ask it about a
single IP address.  Leave out the -xfer when asking about a single IP
address.  

Use the -xfer when you want a dump of an entire prefix such as... 
-xfer 192.168.192.0/19


To ask for a single IP address, just type that in and you should receive
something similar to the below output.


For example,

<prompt> $ telnet rwhois01.somedomain.com 4321
Trying 192.168.221.41...
Connected to rwhois01.somedomain.com (192.168.221.41).
Escape character is '^]'.
%rwhois V-1.5:003eff:00 rwhois01.somedomain.com (by Network Solutions,
Inc. V-1.5.9.5)

192.168.192.1
