The American Registry for Internet Numbers (ARIN) reports that demands for IPv6 address space is growing. According to the 10/19/2009 article, Next-generation Internet defies recession on NetworkWorld, during the first nine months of 2009, ARIN received 300 requests from carriers for blocks of IPv6 address space. This compares to 250 requests received in all of 2008 and 2007.
“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% or 20% year over year.”
Curran says ARIN is beginning to see ISPs such as Comcast and Verizon Wireless put a great deal of effort into migrating from IPv4-based networks to those built using IPv6. “ISPs are asking for IPv6 addresses so they can make their networks IPv6-enabled so they are ready [for the future],” Curran says. “We give each ISP enough IPv6 addresses to support 4 billion networks, and each network can contain trillions and trillions of hosts.”
ARIN’s Curran says the recession is not hampering carriers’ interest in IPv6. “IPv6 solves a problem that hasn’t happened yet. So seeing any demand is surprising, and it means that organizations are planning ahead,” he says. “The current weakness in the economy…is not dampening down IPv6 demand significantly because IPv6 is right around the corner for ISPs. We may be two years away from the IPv4 free pool of addresses running out, but two years, if you’re an ISP, is enough time to get one network deployed. Two years is within everyone’s planning horizon.”
ARIN plans several policy changes to push carriers towards IPv6 adoption. These include:
- Allowing ARIN to reduce the size of IPv4 address space allocations to carriers as the industry gets closer to IPv4 address depletion.
- Increasing access to IPv6 address space by removing the requirement for carriers to first demonstrate that they have hundreds of customers.
- Allowing carriers to run multiple, discrete IPv6 networks that don’t have to be connected to each other, such as community networks.
- Reconsideration of a current policy that requires the regional registries including ARIN to evenly divide up any IPv4 space they are able to recover.

“As utilities are looking to build out smart grid, it’s more effective to agree on a common protocol across the board as opposed to trying intermix different ones,” Hatter says. “In many ways, this is like the early days of the Internet where we ultimately settled on IP. We see IP as the scalable protocol for smart grid and we’re working with a variety of vendors to advocate this and make this the key protocol of choice.”
