Don't Let IPv4 Exhaustion Sneak Up on You

A few months ago, IANA exhausted its unallocated IPv4 address pool when it gave the last /8's to regional registries around the world. That news got a fair amount of buzz. Last month, some of the biggest sites in the world participated in World IPv6 Day to a little fanfare as well. Following those larger flows of attention have been the inevitable ebbs as people go back to "business as usual." As long as ARIN has space available (currently 4.93 /8s in aggregate), no one is losing sleep, but as that number continues decreasing, and the forced transition to incorporate IPv6 will creep closer and closer.

On July 14, I was honored to speak at IPv6 2011: The Time is Now! about how technology is speeding up IPv4 exhaustion and what the transition to IPv6 will mean for content providers. Since the session afforded me a great opportunity to share a high level overview of how I see the IPv4-to-IPv6 transition (along with how SoftLayer has prepared), it might be interesting to the folks out there in the blogosphere:

As time goes by, these kinds of discussions are going to get less theoretical and more practical. The problem with IPv4 is that the entire world is about to run out of free space. The answer IPv6 provides is an allocation pool that is not in danger of exhaustion. The transition from IPv4 to IPv6 isn't as much "glamorous" as it is "necessary," and while the squeeze on IPv4 space may not affect you immediately, you need to be prepared for the inevitability that it will.

3 Bars | 3 Questions: IPv6

Thanks to Marc's vote, I had the distinct honor of being the third guest on our "3 Bars | 3 Questions" series. The topic of conversation: IPv6.

Are we in a "The sky is falling!" situation yet? How can customers put pressure on their ISPs and software providers to add IPv6 support? How long with ARIN and SoftLayer have IPv4 addresses to give out now that IANA has released their entire free pool? Here's my take:

This video was recorded while Kevin was standing outside the Moscone Center in San Francisco at GDC 2011 over a mobile hotspot connection, so the video quality suffered a little. To silence the street noise, Kevin muted his side of the conversation as I spoke.

Is Your Business Ready for World IPv6 Day?

As you may have seen earlier in the week, SoftLayer is joining ISOC's 24-hour IPv6 "test flight" as a part of World IPv6 Day on June 8, 2011.

As I alluded in ISOC's press release, SoftLayer is a hosting provider, but we aren't going to be an effective resource for our customers if we don't adopt the newest technologies and platforms for future growth. Because we've built our business around that idea, you won't see many substantial changes when June 8 rolls around ... We were a little ahead of the curve in December 2008 when we began providing native IPv6 support to our publicly available services. The point of this Internet-wide event is not about getting there first, though ... It's about everyone getting there.

What does World IPv6 day mean to you? Probably little to nothing in the short-run. While there's a unanimous sense of urgency to be prepared, the real deadline is still a little ways into the future. If you're a SoftLayer customer, it's pretty easy for you to take part in your own World IPv6 Day: Provision your free IPv6 /64 on your server and start using them.

I encourage you to set goals for IPv6 functionality for the near future so you don't find yourself scrambling for a solution when you can't get any new IPv4 addresses. Don't let the fact that ARIN still has 5.20 IPv4 /8s in aggregate lull you into inaction ... The well will run dry, and the sooner you're ready for it, the better. Would your business be ready to flip the switch to IPv6 on June 8?
