If you're looking for proof that the adoption of IPv6 is becoming a U.S. phenomenon, take a look at both Comcast and Verizon Wireless. Both of these service providers have decided to migrate from IPv4-based networks to IPv6. According to the American Registry for Internet Numbers (ARIN), U.S.-based service providers interest in IPv6 over IPv4 addresses continues to ramp up.
During the first nine months of this year, ARIN said it received 300 requests from service providers for IPv6 address space blocks. Conversely, ARIN received only 250 IPv6 requests throughout 2007 and 2008. "We're seeing an uptick in IPv6 address space requests; it's a very significant growth rate," says John Curran, president and CEO of ARIN. "We've seen a slight slowdown in IPv4 address space requests... It's probably dropped off 10 percent or 20 percent year over year."
