Google and Its Continuing Dark Fiber Mystery

News Analysis: Analysts say Google may be spending more than $1 billion on infrastructure projects, including purchases of a "dark fiber" backbone. The reason for the purchases is a riddle to the industry, but one Internet consultant r

The market is still guessing about Googles continued purchases of "dark fiber" and what that will mean to the Internet. Yet another explanation was floated at a recent IT conference: IPv6, the next-generation Internet standard.

During a debate on the adoption of Internet Protocol Version 6 at the Burton Groups annual Catalyst conference in San Francisco, Alex Lightman, CEO of IP telephony vendor, offered a new reason for Googles expenditures on dark fiber.

His observation came during a dialogue on Internet addressing and the lack of support by service providers for IPv6. He is worried that the United States is focused on the present and is not addressing future needs.

According to Lightman, some service providers are preparing for IPv6. He ran down a list of companies with "slash 20" addresses.

"You know who else has a big pot of slash 20? Google," Lightman said. "Yahoo does too. Its not that service providers arent doing it—its the savvy service providers, with the high multiples and visionary management, that are getting ready to go into it.

"This is why Google bought mobile dark fiber. Its to go out and go: All these bozos in America arent rolling out IPv6, so well do it if they arent going to," he said.

Lightman said that Google hired Vint Cerf in September 2005 as vice president and chief Internet evangelist in order to lead the companys IPv6 strategy.

Cerf and other IPv6 proponents point to the increasing demand for IP addresses from mobile devices, such as phones and handhelds, but also automobiles. Support for the growing number of static and mobile devices in the world with IPv4 and NAT routers will become problematic some time over the next five to 10 years, analysts said at the Burton conference, disagreeing on whether demand for addresses will become critical sooner.

With IPv6, the Internet will be able to handle trillions of individual addresses.

According to telecom industry reports, Google said its capital expenditures will exceed the $800 million in 2005. Analysts suggest that the actual amount may be in the $1.25 billion range. Some suggest that a portion of this investment is going into purchases of dark fiber, or unused fiber-optic telecommunications infrastructure built in the late 1990s.

What Google is doing now with the global infrastructure—or, more to the point, what it plans to do in the future—has sparked plenty of speculation in the telecommunications and computer industry. Aside from the IPv6 applications and services theory proposed by Lightman, other candidates have included the following:

  • Google Wi-Fi. Google is moving forward with municipal Wi-Fi networking plans for Mountain View, Calif., near its headquarters as well as San Francisco, being built by Internet provider EarthLink, and possibly one in New Orleans. The dark fiber backbone could give the company leverage for expansion to other cities and states, even allowing the company to take over as a provider.
