I'm not sure why this is being up-voted so much. It won't work. SOPA works by not routing specific IPs, not by failing to resolve domains (which is why it fundamentally breaks the internet). Additionally, a single IP won't work for a major site like YouTube or Facebook, which work off multiple data-centers and CDNs (which also complicates how to "block" a site served by 50 IPs that may also be distributing content for another major brand). This is bigger than a hosts file.

SOPA works by failing to resolve domain names, it does nothing to stop a user from entering a particular IP address.

Like everyone has been saying, it. does. nothing. good.

I don't think that's true. According to http://news.cnet.com/8301-31921_3-57328045-281/sopas-latest-...

Cary Sherman, the head of the Recording Industry Association of America, wrote in a guest column for CNET that SOPA could be used to force Internet providers to block by "Internet Protocol [IP] address" and deny "access to only the illegal part of the site." The RIAA, along with the Motion Picture Association of America and the U.S. Chamber of Commerce, strongly supports the legislation.

An aide to the House Judiciary committee -- chaired by Rep. Lamar Smith (R-Tex.), SOPA's principal sponsor -- did not dispute that IP address blocking and deep packet inspection could be required. It would be up to a judge to determine the nature of the court order that would be needed to block the site, the aide told CNET this afternoon.

They are definitely looking to block by IP, not just DNS.
