First New gTLDs Get the Green Light for Delegation

Posted October 21st, 2013

From ICANN Blog

Today, the first four domains from ICANN’s New Generic Top-Level Domains Program were cleared to proceed to delegation. This marks the start of a measured roll out of new gTLDs, which are designed to expand opportunities for businesses, communities and Internet users around the world.

These first new gTLDs, or strings, are:

  • شبكة (xn--ngbc5azd) – the Arabic word for “Web” or “Network”
    Registry : International Domain Registry Pty. Ltd.
  • онлайн (xn--80asehdb) – Russian for “Online”
    Registry: Core Association
  • сайт (xn--80aswg) – Russian for “Web site”
    Registry: Core Association
  • 游戏 (xn--unup4y) – Chinese for “Game”
    Registry: Spring Fields, LLC

The Skinny on IPv6

Posted October 18th, 2013


So what is IPv6, and why do I need to know about it?

IPv6 or IP version 6 is the next generation Internet protocol which will eventually replace the current protocol IPv4. IPv6 has a number of improvements and simplifications when compared to IPv4. The primary difference is that IPv6 uses 128 bit addresses as compared to the 32 bit addresses used with IPv4. This means that there are more available IP addresses using IPv6 than are available with IPv4 alone. For a very clear comparison, in IPv4 there is a total of 4,294,967,296 IP addresses. With IPv6, there is a total of 18,446,744,073,709,551,616 IP addresses in a single /64 allocation.

To also help illustrate the sheer magnitude of available IP addresses using IPv6, you can get 65536 /64 allocations out of a single /48, and then 65536 /48 allocations out of a single /32. Many Service Providers are getting /32 allocations from their Regional Internet Registry (RIR) like ARIN, APNIC, RIPE, etc.

A significant difference between IPv6 and IPv4 is the address notation. IPv4 uses a period (.) between each octet, compared to IPv6 which uses a colon (:). With IPv6, if you have a series of zeroes in a row, the address need not be written out completely. You can use a double colon (::) to represent that series of zeroes, however you can only use that once. For example, if you have an address like “2001:0DB8:0000:0003:0000:01FF:0000:002E”, it can be written like “2001:DB8::3:0:1FF:0:2E” or “2001:DB8:0:3:0:1FF::2E”, but would never be written like “2001:DB8::3::1ff::2E”. You also cannot have three colons in a row (:::).

IPv6 availability depends on your Service Provider, either at home or for work. In a dual-stack environment, IPv4 and IPv6 co-exist along the same connection and don’t require any special kind of connection. If dual-stack is not available, you might find yourself using an IP tunneling product or service to bring IPv6 connectivity to you. Even though IPv4 exhaustion has happened at IANA, IPv4 won’t simply disappear off the face of the Internet, but continued explosive growth requiring more unique IP address assignments will mean using more and more of the abundant IPv6 address space.

Many Operating System platforms have native IPv6 support these days. The UNIX based platforms like Linux, BSD (Free, Open, Net) & MacOSX have had IPv6 support enabled for years now. Microsoft Windows starting having native IPv6 support enabled by default with its Vista and Windows 2008 products. Earlier Windows versions like 2000/2003/XP had to have it installed optionally, and did not have as robust features that are available in the newer versions of Windows. Even common web browsing and email software will use IPv6 if it is enabled and available, without having to check off an option or special configuration. The transition from IPv4 to IPv6 is being worked on to be as seamless as possible, and many might not even notice the subtle changes in the coming years.

Remembering Jon Postel

Posted October 17th, 2013


On October 16, 1998, Jon Postel died at the age of 55. The impact of the technical and organizational improvements he made to the Internet during his all too brief life is immeasurable.

At the time of his death, Jon had been working tirelessly to create an entity to manage and maintain the Internet’s address directory – ICANN.

Numerous tributes followed Jon Postel’s death and they continue today. Please take advantage of the links provided below to read about Jon Postel and listen to the remembrances of three Internet pioneers who knew him well.

For more information about Jon Postel, please visit the following pages:

Wired Magazine: Remembering Jon Postel – And the Day He Hijacked the Internet

“If Jon were here, I am sure he would urge us not to mourn his passing but to celebrate his life and his contributions. He would remind us that there is still much work to be done and that we now have the responsibility and the opportunity to do our part. I doubt that anyone could possibly duplicate his record, but it stands as a measure of one man’s astonishing contribution to a community he knew and loved.”
