Network Solutions and GoDaddy said they make customer information available to official parties, but keep it hidden from casual seekers. "It's not intended to be Switzerland. It's just intended to give law-abiding citizens a right to privacy," Parsons said.
GoDaddy has provided proxy services for 23,000 of the 311,000 .us addresses it has sold, according to the company. Network Solutions, based in Herndon, Va., has sold roughly 78,000 .us addresses and acts as a proxy for 2,500 of them, according to chief executive Champ Mitchell.
Mitchell said that although .us addresses are a "minuscule" part of the company's business, Network Solutions will "do everything in its power" to protect the privacy of its hundreds of thousands of proxy customers in all domains.
Neither company would make any of its proxy customers available for immediate comment. Parsons said he has been discussing the policy on his blog at
www.bobparsons.com and that some users have e-mailed him expressing fear that their personal data will be made public.
Mitchell and Parsons said they will appeal to the Commerce Department and to Congress to overturn the decision before it takes full effect in January.
