Verizon: We have plenty of IPv4 addresses

Carolyn Duffy Marsan | March 7, 2011
Verizon Business says it has enough IP addresses using the current version of the Internet Protocol, known as IPv4, to support its U.S. business and government customers as they transition to the next-generation standard, IPv6.

"Government agencies, telecom carriers and content providers are definitely adopting IPv6 in a much more serious way over the past six months than they have historically," Mardis says. "U.S. enterprise customers are concerned about supply chain management" if they have suppliers in Asia where carriers are running out of IPv4 address space.

Another driver: World IPv6 Day, a 24-hour trial of IPv6 that is scheduled for June 8. Sponsored by the Internet Society, World IPv6 Day has attracted some of the largest Internet content providers and high-tech companies, including Google, Facebook, Yahoo, Microsoft, Cisco and Juniper.

World IPv6 Day "is piquing people's interest," Mardis says. "This is completely anecdotal ... but it's triggering them to want to have an IPv6 circuit or two up so they can test on World IPv6 Day."

Verizon says it is seeing more demand for IPv6 services from its enterprise customers than its residential customers. The carrier held a small trial of IPv6 services on its all-fiber FiOS network in northern Virginia last spring.
