Fast WHOIS lookup

[Marc Perkel]

I'm doing some research using WHOIS to find the owners of domains in the 
URI blocklists and finding that many of them have the same owners. I 
thing that a database of owners of the URIs that spam links to could be 
extremely useful in detecting spam.. I;m seeing that a huge amount of 
spam is owned by optinrealbig.com

Is there any fast and efficient way to pipe a bunch of URIs into a 
program and return owners?
