The World of Domain Name Developers group asked the court to stop the nonprofit body overseeing the Internet's addressing system--the Internet Corporation for Assigned Names and Numbers, or--from until 2012.
That proposed deal, reached in October, settled aand is expected to be finalized by the end of the year.
The lawsuit, which was filed in federal court in San Jose on Monday, said the proposed settlement violates federal laws against price fixing and creates a monolopy of the .com and .net domain name markets.
Plaintiffs' attorney Patrick Cathcart said the settlement fixes the price of registering any .com or .net far above market rates. He also said terms of the settlement guarantee VeriSign annual price increases at double the rate of inflation.
ICANN, which is based in Marina del Rey, Calif., could not be reached for comment while a spokesman for Mountain View, Calif.-based VeriSign declined to comment on pending litigation.
The original dispute between VeriSign and ICANN arose after VeriSign introduced a new service called Site Finder in September 2003, directing Internet users who mistyped domain names to a VeriSign site that allowed consumers to choose from a list of alternative names. VeriSign planned to make money by selling advertisements on the site.
ICANN ordered VeriSign to temporarily, after engineers said it could interfere with the stability of the Internet.
VeriSign then sued in February 2004, saying the Internet body had overstepped its authority and illegally restrained competition. Thein August 2004, but state court.
The two parties reached a proposed settlement in October, in which VeriSign maintained control of the database of 35 million .com domain names until 2012. The contract would have otherwise come up for renewal in 2007.
VeriSign makes $6 per year from each of the 35 million .com domain names in use. It also controls the .net domain, which contains nearly 6 million names.
The settlement also requires ICANN to review within 90 days new products or services introduced by VeriSign and its competitors that might affect the domain name system.
