Verizon: Businesses need to move on IPv6

By , Network World |  Internet, IPv6

Verizon Business has a message to companies still reluctant to migrate their networks to IPv6: You're better off doing it now than later.

William Schmidlapp, Verizon Business's product manager for Internet dedicated access services, says that the advent of 4G LTE and WiMAX-based devices will only increase the need to switch over to IPv6, since each of those devices will require its own IP address. So if any company wants to push its content out to mobile devices over the next few years, they're going to need some capability to handle IPv6 traffic.

"If every phone in China becomes a smartphone, then every phone will need an IP address," explains Waliur Rahman, Verizon's technical manager for IPv6 services. "So you're going to have to include IPv6 as part of your network architecture."

IPv6 is a next-generation Internet layer protocol that was designed by the Internet Engineering Task Force (IETF) to solve the problem of IP address depletion under the current Internet layer protocol, IPv4. While IPv4 has a fixed limit of around 4 billion IP addresses, IPv6 will have exponentially more, on the magnitude of around 340 billion billion billion billion (3.4×1038). The trouble that IPv6 advocates and ISPs have run into so far, however, is that many of the ISPs' enterprise customers don't see the logic in investing time and money in IPv6 deployment during a recession where they have far more pressing and immediate needs, even though IPv4 addresses are projected to be depleted sometime within the next year.

Jason Schiller, Verizon's senior Internet network engineer, says that part of the challenge for CTOs and IT departments is understanding that upgrading to IPv6 doesn't necessarily have to be a costly process that will upend all of their current architecture. In reality, they may have to replace some of their hardware, but they can also use software upgrades to solve their IPv6 needs, especially if they're a smaller firm that doesn't handle large amounts of network traffic.

"Smaller networks that have lower throughput and traffic can be upgraded through software," he says. "I'm not saying that's going to be cheap, though. In some cases the software contract can be expensive and sometimes you'll have to upgrade your routing engine as well. And for some networks, you'll have to go through some significant testing of IPv6 in a lab to make sure it can do everything you need."
