And I should thank you for that lesson. I have added "whois.cymru.com" to my 
Sam Spade Win Tools application, using this link:

http://www.samspade.org/ssw/tips.html

Going down to the "Adding whois servers" section, and following the 
directions. I haven't taken time to see if I can automate the process any 
further; currently I get a result with Sam Spade:

-----------------
02/05/05 16:23:30 whois 68.142.234.38 at whois.cymru.com

whois -h whois.cymru.com 68.142.234.38 ...
ASN     | IP               | Name                          
14779   | 68.142.234.38    | INKT Inktomi Corporation      
-----------------

I can then surf to this bookmarked link to fill in the final pieces of the 
puzzle:

http://bgp.potaroo.net/cgi-bin/as-report?as=AS

I can open the page on that link, then past the Sam Spade ASN result to the 
end of the link to get something like:
