A total of 32 percent of ISPs offer IPv6 services to business customers today, according to a new European Commission-funded survey, said John Curran, chief executive of American Registry for Internet Numbers (ARIN), one of the world's five nonprofit Internet registry organizations that collectively hand out Internet addresses and keep track of which numeric addresses are connected to which servers on the Internet.

That percentage, though, is increasing.

"Sixty percent intend to have services within a year. That's a huge step up," Curran said. "Within two years, it is 80 percent."
