With more and more companies and individuals coming away against the Blockage Online Piracy Routine (SOPA), the source of the Senate version on Thursday foreboded to study how his greenback might impact the Domain Refer Organisation (DNS).

SOPA, currently being thought in the House, and the PROTECT IP Bit (PIPA), which is making its way through the Senate, both choke later so-called “rogue” overseas Web sites that traffic in counterfeit goods—from fake handbags to prescription drugs. The bills would permit the Justice Department to induce a court gild to shut down these sites and strike them from search engines. Detractors, however, argue that the bills are also wide and far-reaching, and could receive unintended consequences on legitimate, U.S.-based Web sites.

Sen. Patrick Leahy, a Vermont Democrat and source of PIPA, said on Thursday that he is prepping an amendment to the bank-bill that would require a canvass into the effects of the bill before it is implemented.

“Through this process, [I] receive continued to discover concerns nigh the Domain Refer supply from engineers, human rights groups, and others,” Leahy said. “I rest confident that the ISPs—including the cable industry, which is the largest association of ISPs—would not tolerate the legislation if its enactment made the problems that opponents of this provision suggest. Nonetheless, this is in fact a highly technical issue, and I am machinated to recommend we reach it more analyze ahead implementing it.”

While one might argue that it would exist best to pattern away the branches of a bill before balloting it into law, Sen. Leahy pronounced the major issues that SOPA and PIPA would address must be addressed as presently equally possible. The study, Leahy argued, will let lawmakers to “focus on the other important provisions in this bill, which are essential to protecting American intellectual property online, and the American jobs that are tied to intellectual property.”
