The question of how and where enterprises should move to IPv4 was tackled in a panel discussion at the Interop conference in Las Vegas this week.
While IPv6 traffic historically has been minimal, there has been a recent surge of activity due to the exhaustion of the free pool of IPv4 address space.
In terms of where current adoption is for IPv6, Martin Levy, Director IPv6 Strategy at Hurricane Electric noted that there are lots of IPv6 enabled services. He said there are IPv6 enabled service providers, operating systems and hardware all in the market today.
According to Levy, on May 3rd, IPv6 usage hit 10 percent of the Internet, which is the first time that IPv6 has hit double digit usage.
Going out a step further, Levy argued that 50 percent of well connected network service providers today are already IPv6 enabled. Levy defined "well connected" as service providers with connections to eight or more networks.
"But what about the other 50 percent?" Levy asked the audience. "Ask your service provider or maybe pick another one, you don't have an excuse anymore."
