Internet industry wary of domain expansion

– A plan to dramatically expand the numbers of possible Web addresses – by adding more than 1,000 new domains such as “.buy,” “.casino” and “.gay” – could cause widespread disruption to Internet operations, say some industry officials.

Efforts to augment existing domains such as “.com” and “.gov” have been underway for several years and are entering a critical phase as industry officials meet at an international conference that began Sunday in Durban, South Africa.

By summer’s end, the new domains could be going live at a pace of 20 or more each week.

The plan has touched off a scramble among investors eager to gain control of the virgin Internet real estate, potentially worth billions of dollars in annual licensing fees. But a vocal group of critics is calling the speed and scale of the expansion reckless, given its possible effect on the Internet’s global infrastructure, which relies on interactions among computer networks owned by companies, universities and individual users.

Particularly troubling is the possibility of widespread “name collisions” that could happen when domains used by internal corporate computer systems – such as “.corp” or “.home” – get assigned to the Web more broadly. This could cause systems to fail, blocking access to email or other internal programs, and also could open sensitive information to theft, some experts say.

“This could affect a million enterprises,” said Danny McPherson, chief security officer for Verisign, which is based in Reston, Va., and manages several of the most popular existing domains. “It could absolutely break things.”

McPherson and other security experts say the nonprofit group that oversees the designation of Web addresses, the Internet Corporation for Assigned Names and Numbers (usually known by its acronym, ICANN), has not done enough study on the effect of the new domain names and does not have procedures in place to respond quickly if systems malfunction. Among those posing risk could be domains such as “.med” or “.center” that might be critical to the functioning of medical systems or emergency-response networks.

Similar concerns have been expressed by the Association of National Advertisers and the Internet commerce site PayPal.

Defenders of the plan have called such fears overblown, arguing that the potential problems have been long understood and will be resolved before new domains are approved. Because the new domains will be released gradually, over the course of months, there will be time to manage problems as they arise, said Jeffrey Moss, chief security officer for ICANN.

“It’s not like it’s a runaway train without recourse,” Moss said. “We’re not going to do anything that harms the security or stability of the Internet.”

U.S. officials who oversee Web security issues through the Commerce Department’s National Telecommunications and Information Administration expressed confidence in the domain program, issuing a statement saying, “We would expect these issues to be discussed and resolved within the ICANN multistakeholder process.”

Donuts Inc., an investment group that made the largest number of bids, with 307, said Verisign’s criticism of the process for launching the new domains was a result of self-interest. The company controls the popular “.com” and “.net” domains, giving it a degree of market power that could be diluted.

“ICANN was created in large part to break Verisign’s monopoly over domain names,” Donuts spokesman Mason Cole said in a statement. “Now that the organization is on the verge of achieving that goal, it’s not surprising that Verisign is uncomfortable.”
