Happy IPv6 Day!

Today, major technology players like Google, Facebook, Yahoo, YouTube, Cisco and others will take part in a 24-hour test flight of the next generation Internet protocol.

This exercise is to gauge how smooth or pain-riddled the transition from IPv4 to IPv6 will be. 
When does the testing start? For those in New York, testing began on Tuesday, June 7 at 8pm and will end Wednesday, June 8 at 8pm. Everyone can check start and finish times in their local areas at 
Remember, IP addresses are unique numbers received by every device that connects to the Internet (or a private network), so that those devices can communicate with other devices on the same network. Websites and email domains (for instance, the part of an email address) also have associated IP addresses.
This addressing system is known as Internet Protocol and is currently at version 4; hence IPv4. We've been using IPv4 addresses since the early 1980s. There was a finite amount of IPv4 addresses available, however, and they have now been exhausted.
IPv4 uses a system of numbers, typically separated by decimals, that even casual users of the Internet would probably recognize (if you are unsure, check your computer or phone's network settings for numbers like "").IPv4 had about 4.3 billion addresses, which ran out more rapidly once mobile devices with Internet connections became commonplace.
Now all new Internet addresses will use IPv6, a system that has more numbers and characters, and is said to have enough spots for 340 trillion, trillion, trillion unique IP addresses. Equipment that uses IPv6 has been in use since 1999.

Although IPv6 has been available since the '90s, not many companies, ISPs, or other organizations have implemented it. Most are still on IPv4. That is changing, though, as governments, corporations, ISP, and MSOs (Multiple System Operators) map out their plans to transition. Of course, the likely scenario is that many networks will run both IPv4 and IPv6 in tandem (called dual-stacking) for a while until IPv6 becomes the standard.
Home users and small business owners should not have too much to worry about: chances are your ISP or the provider hosting your Web site or domain will ensure your transition to IPv6 is fairly seamless—it's the larger enterprises that have to be more proactive. No matter the size of your business, however, you should contact your ISP or Web-hosting service to find out what their plans are for IPv6.
While there should be no panic about the fact that the world has officially run out of IPv4 addresses, vigilance is a best practice, especially for small business owners. But even home users can take precautions to ensure that their home networks are ready for what is most likely to be a gradual transition.


  1. alright...thx for the link

  2. Nice blog man, I'm following and whatnot.

  3. I heard about IPV6 earlier actually, I'm interested to see if it actually makes a difference.

    Informative post and nice looking blog, followed.

    Take a look at mine sometime:
