Proposed US Bill Requires ISPs to [Use DPI] Block Sites by Domain Name

 

A proposed law in the US - SOPA (Stop Online Piracy Act) says that "A service provider shall take technically feasible and reasonable measures designed to prevent access by its subscribers located within the United States to the foreign infringing site (or portion thereof) that is subject to the order, including measures designed to prevent the domain name of the foreign infringing site (or portion thereof) from resolving to that domain name’s Internet Protocol address".

Similar initiative in the UK led local regulator, Ofcom, to check if this is possible to do, even with DPI. The result was - No - "All site blocking techniques can be circumvented" (here).Nevertheless, a UK court recently ordered BT to block on size (Newzbin2) and use DPI to do so (here).
