World IPv6 Day

On June 8, NASA joins organizations from across the globe to test out the next generation of the Internet, called Internet Protocol version six or IPv6. As more devices and people come online, the older Internet Protocol version four (IPv4) addresses — those sets of numbers that uniquely identify every device on the Internet — are rapidly running out, making a new series of addresses and protocols necessary. That’s where IPv6 comes in since it uses longer strings of numbers and letters to create new addresses.

Upgrading to IPv6 means we can have far more addresses for the continued growth of the Internet. Nearly 20 years ago, a similar upgrade happened to the telephone system in North America when ten-digit dialing became the norm, which greatly expanded the availability of telephone numbers. This Internet upgrade also presents challenges as entire networks from industry, government and universities must be overhauled to simultaneously support both IPv4 and IPv6 — hence the need for a test day.

Other organizations such as Google, Facebook and Yahoo will be among those participating in World IPv6 Day on June 8 for a 24-hour ‘test flight’ of the new IPv6 running from midnight UTC to midnight UTC a day later. The organizations participating in World IPv6 Day hope that the test will provide the motivation for Internet service providers, hardware makers, operating system vendors and other Web companies to prepare their services for IPv6 and to ensure a successful transition as the old IPv4 addresses run out.

During World IPv6 Day, the following NASA websites will be reachable via IPv6 for 24 hours:

Let us know if you are testing out the IPv6 sites! For more information on World IPv6 Day, please see

  1. Try three sites and downloaded badge. Opera Swordfish Browser. No problems in visiting three sites.

  2. What would I do without the net right now? I guess I would be fast a sleep right now.

    gotta love technology 🙂

  3. All of the links worked except the I got the message below when I tried to link to the images on the page. The primary image of the volcano did not even show up.

    The requested URL /IOTD/view.php was not found on this server.

  4. I’m doing my little bit. Visited all the IPv6 links, no problems. Used Android phone browser.

  5. The sites seemed to work just fine. However, when I pinged
    I got an ipv4 address (

  6. Urm… you might have a problem… I am getting “Apache 2 Test Page” when visiting the and sites… (on a dual-stack connection)

  7. Really its a new creation by NASA thanks for sharing this we got latest news about NASA
