Rehearsals over, IPv6 hits Broadway June 6

To follow-up my post from last week where the South Florida Technology Alliance (SFTA) sponsored our IPv6 Event where we had the CEO of ARIN.Net, John Curran, speak about World IPv6 Launch Day, well it has arrived! By the time most of you get around to reading this post, IPv6 will have been enabled on 2,500 websites (where you might be reading this post as well) such as Google, YouTube, Facebook and Yahoo along with 50+ access networks across the Internet. Again this is NOT a Y2K or “The Sky is Falling” prediction but just an alert that you should be in contact with your respective ISP(s) to ensure that they have completed what is necessary to insure your connectivity to the Internet as they will be running BOTH IPv4 and IPv6 for several years to come. This is a very important step in the continued growth of the Internet as we know it so the SFTA wants to insure that this important message is cascaded out to our membership and their respective communities of influence. Additional information on my previous post and information about World IPv6 Launch Day is listed below. Thanks!

Network World Article on World IPv6 Launch Day

14 years after next-gen Internet Protocol was created, World IPv6 Launch Day looms

IPv6 will go fully live on June 6. That’s the date when 50-plus access networks and more than 2,500 websites — including Google, YouTube, Facebook and Yahoo — will turn on support for the long-anticipated upgrade to the Internet’s main communications protocol and leave it on for good.

World IPv6 Launch Day is being coordinated by the Internet Society, which is promoting IPv6 as the best strategy for ensuring that the Internet continues to grow as address space becomes increasingly scarce with IPv4, the original version of the Internet Protocol.

Participants in World IPv6 Launch Day are trying to drive home the message to techies worldwide that it’s time to start deploying IPv6.

“If you’ve been waiting to deploy IPv6, there is no reason to continue waiting,” says Leslie Daigle, chief Internet technology   officer with the Internet Society (ISOC). “There are customers who will view your website over IPv6 now. It isn’t experimental.   It’s out there for real.”

Some of the largest ISPs have signed on for World IPv6 Day, including Comcast, AT&T, Verizon Wireless and Time Warner here in the United States. Each has agreed to enable IPv6 for 1% of their subscribers by Wednesday.

Comcast met its goal of IPv6-enabling 1% of its subscribers on May 24.

“We’ve launched IPv6 to a third of our network at this point,” said John Brzozowski, chief architect for IPv6 and distinguished   engineer with Comcast. “We will be deploying it to the rest of our network over the balance of this year and likely beyond   2012. At this point, the momentum is there for IPv6, and we are making significant strides in penetration and the number of people that have IPV6 available to them.”

Equally significant is the participation by content delivery networks such as Akamai and Limelight. Akamai carries between 20% and 30% of the Internet’s Web traffic on any given day, so its support of IPv6 is a boon for the new  protocol. Among Akamai’s customers are Apple, Lands’ End, Ticketmaster and Travelocity.

World IPv6 Launch Day is designed to “send enough IPv6 traffic toward content providers to give them confidence that the big   access providers are serious about IPv6 and that they should leave it on at their front doors,” Daigle says.

Thousands of popular websites have agreed to permanently enable IPv6 by Wednesday. Some, including Facebook, have already   turned on IPv6 in production mode. Other World IPv6 Launch Day participants include: consumer-oriented websites such as Bing   and Netflix; U.S. government agencies including NASA and the Census Bureau; universities such as Indiana University and the   University of Pennsylvania; and network vendors such as Cisco and Check Point.

“World IPv6 Launch Day is a lot larger than people understand,” says John Curran, president and CEO of the American Registry   for Internet Numbers (ARIN), which doles out IPv4 and IPv6 addresses to network operators in North America. “It’s not a small   decision for the major content providers to turn on IPv6 and leave it on. From now on, everything they roll out will be on   IPv4 and IPv6.”

Additionally, four home networking equipment manufacturers — Cisco, D-Link, NDM Systems and ZyXel Communications — have   agreed to enable IPv6 by default on their home router products by the June 6 deadline.

“There are other home router vendors that are mostly there [with IPv6 support] but for one reason or another haven’t gone   through the certification process,” Daigle says. “We have definitely met our mark in terms of raising awareness with the CPE   equipment vendors that IPv6 is real.”

Created in 1998 by the Internet Engineering Task Force, IPv6 offers an expanded addressing scheme but is not backward compatible   with IPv4. While IPv4 uses 32-bit addresses and can support 4.3 billion devices connected directly to the Internet, IPv6 uses   128-bit addresses and can connect up a virtually unlimited number of devices: 2 to the 128th power.

The Internet needs IPv6 because it is running out of IPv4 address space. The free pool of unassigned IPv4 addresses expired   in February 2011, and in April 2011 the Asia-Pacific region ran out of all but a few IPv4 addresses being held in reserve   for startups. The European registry is expected to deplete its supply of IPv4 addresses in August, and ARIN next summer.

Network and website operators have two choices when it comes to IPv6: They can either support both protocols in what’s called   dual-stack mode, or translate between IPv4 and IPv6. Until now, most have been unwilling to make the upgrades required to   support IPv6 because IPv6 traffic has been so scarce.

That’s expected to change after June 6, when IPv6 traffic is expected to surge. While the most recent estimates are that IPv6   represents less than 0.5% of all Internet traffic, participants in World IPv6 Launch Day are hoping to drive IPv6 up to 1%   or more of Internet traffic.

“One [college] campus expects that on June 6, 50% percent of its network traffic will be IPv6 because its top four most-visited   sites are participating in World IPv6 Launch Day,” Daigle says. “It might surprise some enterprises how much IPv6 traffic   they will see if their users are going to Google, Facebook or Yahoo.”

The anticipated surge of IPv6 traffic after June 6 is expected to bring new security threats along with it.

In February, Arbor Networks reported the first-ever IPv6-based distributed denial-of-service attacks. While IPv6 security incidents remain rare, experts predict   that as more Internet traffic flows over IPv6, DDoS attacks, malware and other threats will follow.

Experts say enterprise network managers should upgrade their DDoS detection, intrusion protection and deep packet inspection   systems to support IPv6.

“It’s time for the enterprise to make sure that their security devices are IPv6-enabled, that they have the ability to look   at IPv6 traffic and to create rules for it and do intrusion detection,” advises Bob Hinden, one of the creators of IPv6 and   a Check Point fellow. “Most host operating systems — Windows Vista, 7, Mac OS, Linux, IOS and Android — all have IPv6 in them. Even though they may not think they have IPv6 turned on, there might be tunneled traffic coming from outside their enterprise. It’s important that the enterprise know what’s going on with IPv6 in their network.”
