Last week I talked a bit about online piracy and the help you can get using the DMCA. Some people were interested in learning how to figure out which ISP hosts the offending website. Here is a link that may help. The National Professional Photographers Assn. has many of the same concerns we writers do in this regard. The NPPA suggests searching for the provider through a website such as http://www.whois.net, or using a DNS lookup like http://www.domaintools.com/research/dns/.
(Now you're all going to think I know a lot about this stuff, since I'm tossing around terms like DNS. So not true. One can use a phrase appropriately without understanding what it means, as I learned a long time ago in a cafe in Aix-en-Provence. A pair of French university students taught me a "very useful saying," but when I repeated it aloud, the couple at the next table left in high dudgeon.)
