SAN FRANCISCO--Although it's been hard for companies to financially justify the expense of embracing the next-generation standard for wiring together the Internet, the incentives are now arriving--and Google itself stands to benefit from the resulting democratization of networking.
Google thinks the time is ripe to begin adopting Internet Protocol version 6. The search giant, which handles gargantuan amounts of traffic, has gradually been making more of its Web properties available over IPv6, which despite being defined for more than a decade still is rare compared to the current IPv4.
The company has been gradually making its properties available over the new standard, starting with an IPv6 access to its search engine in March 2008. The range of other Google properties similarly available expanded to include Google Maps last week, said Lorenzo Colitti, a Google network engineer who spoke Wednesday at a Internet Society panel discussion at an Internet Engineering Task Force meeting here.

Although 4.3 billion may sound like a lot, addresses are often allocated in large blocks that mean many aren't generally available, and expert estimates forecast an end to new IPv4 addresses in 2011.
