Get Ready to Kiss IPv4 Goodbye: Q&A With ICSA Labs' Guy Snyder, Part 1

Get Ready to Kiss IPv4 Goodbye: Q&A With ICSA Labs' Guy Snyder, Part 1

Pressure to implement IPv6 is coming from both public and private sectors. "Based on these statistics, we can look out into the future and say pretty much for sure these are going to go away within the next 10 to 12 months, at least by the end of next year," said Guy Snyder, secure communications program manager at ICSA Labs.

The Obama administration has recently turned up the heat on moving to IPv6, the next version of the Internet protocol after the one currently in use, IPv4. Federal CIO Vivek Kundra issued a memo Sept. 28 instructing CIOs of executive departments and agencies in the federal government to take several actions, including enabling the use of native IPv6, by the end of 2012.

Here's the kicker, though: Agencies will continue running both IPv4 and IPv6 simultaneously "into the foreseeable future" to ensure interoperability, Kundra instructed.

Pressure to implement IPv6 is also coming from major networking vendors, who contend that we're running out of IPv4 Internet addresses. The IEEE made the exact same claim 14 years ago but it seems the alarm was a bit premature at the time.

Has anything changed now? How is it that IPv4 addresses are still available, 14 years after the IEEE said they'd run out?

To answer these questions, TechNewsWorld spoke with Guy Snyder, secure communications program manager at ICSA Labs, an independent division of Verizon Business.

TNW: Apparently the deadline for having products tested for the USGv6 Testing Program, which certifies them for IPv6, has been ignored. Please elaborate.

Guy Snyder: The countdown to July 1 wasn't totally ignored. There have been several vendors that have paid attention to that, there have been agencies that have paid attention to that, there have been several major and minor vendors that have had their products tested, and there are many others that have been preparing for it and their products aren't quite ready.

TNW: In that case, why did Vivek Kundra have to come up with his memo?

Snyder: I think there was more on the government side of things because there still was, from my perspective, from his perspective, and from half of the vendors' perspectives, not enough pressure and not enough teeth in this USGv6 program.

You hear from many vendors when things like this come out that the government has done this in the past and it doesn't always follow through with things in general.

TNW: I saw the note saying there's only 120 days left before IPv4 addresses run out. That's accurate?

Snyder: I don't want to say there's only 120 days left because the first deadline for them coming up with the plan is just a plan, the first deadline for them to put their products in place is the end of 2012.

To do that they have to have products purchased long in advance, and to have products purchased in advance of that date, they have to have them tested before that. And, before that, the products have to be developed and ready for testing. So that's the backlog and that explains the urgency.

TNW: Perhaps about 15 years ago the IEEE first warned that we were running out of IPv4 addresses and said that China and India, with their billions of people expected to come online, would desperately need more addresses. The IEEE urged everyone to switch over to IPv6.

Yet ICSA Labs now says we'll run out of IPv4 addresses by when, March 2011? How can you be so sure?

Snyder: We can be sure because we are now so much closer to it and, before, it was more speculative. When the IETF and everybody said that before, it was true speculation, and now there's numbers to back up where we're going.

We know for a fact that there are only five percent of the IPv4 addresses left, and we know at what rate the numbers are going away and how many have gone away for the past six months.

Based on these statistics, we can look out into the future and say pretty much for sure these are going to go away within the next 10 to 12 months, at least by the end of next year, but most people are saying they'll go away somewhere in the middle of spring or towards the end of next year.

TNW: Perhaps Network Address Translators and subdomains helped alleviate the problem?

Snyder: They could have, but it's part of the issue and that could continue to be a reason why the date would extend out, but I sincerely doubt that will happen at this point.

At that time nobody had any numbers; we had a new technology and thought everybody would switch over to the new technology. We knew the Japanese were moving towards Ipv6, and the Chinese, but they didn't move as quickly as we expected.
