6 things you should know about IPv6, which begins running today

6 things you should know about IPv6, which begins running today

Today June 6 is the worldwide launch of IPv6, the new protocol, which will go permanently. Last year we did a test one day , to test how such systems worked, but now it’s time to welcome the “new internet” permanently.

What does that begin running the new protocol? We review some key concepts in this post.

What is IPv6?

IP addresses are those that enable communication on the Internet. When trying to enter a website, for example, your computer sends a request to a server, to deploy the site on your screen. That requirement is not lost because he knows where to go: that direction is given in a series of numbers corresponding to the site, while your own computer is also identified by a number of different numbers, which allows packets coming back.

Since 1981 he has been using the version 4 (or IPv4), which operate most Internet communications. uses 32-bit, allowing a total of 2 ^ 32 addresses (or addresses 4.294,967.296 total). That was very much in the 80′s, but with the development of the web, IPv4 addresses already virtually exhausted.

The solution is IPv6, the next evolution of the protocol, which uses 128-bit addresses, allowing 2 ^ 128 series of numbers (about 340 sextillion addresses). The idea is to reach not only computers that will connect to the Internet, but also for smartphones, tablets, and other intelligent devices that might arise. development was completed in 1996 and the first networks and could be built in 1999, however, the implementation of the system has taken time.

IPv6 also implements several new features and simplifies some aspects, adding more security in its architecture.

If today we started using IPv6, IPv4 is it just?

No. Although it is the global launch, many companies worldwide have implemented IPv6 yet and continue to use IPv4 addresses. This is especially true in Latin America, the geographic region that has more IPv4 addresses available.

Latin America and the Caribbean still have reservations until 2014, which means that our region is likely to progress slower than the rest in IPv6.

IPv6 creates a “separate internet”?

The problem is that IPv6 is not interoperable with IPv4, but works in parallel, creating a separate Internet which now exists. For example, if a person enters a room in an IPv6 address, and tries to communicate with another (through a link for example) running on IPv4, you might get an error message. Conversely, there will be people who can not get to sites that have only IPv6 address if your ISP does not support this protocol. To review what position you are, you can check your status at this link .

Now to the internet does not “break” in two, you should implement systems for “translation” to change from IPv6 to IPv4 (and vice versa) without the appearance of errors. For this we used a technique called ” tunneling “, which encapsulates the packets so they can move from one to another without getting lost.

What ISPs are ready to support IPv6?

On the site of the Latin American and Caribbean Internet Addresses Registry (LACNIC) is a list of organizations that are already supporting IPv6. Among the ISPs listed are the only GTD and VTR in Chile, Argentina and Telecom Telmex Colombia.

Telefónica issued a statement yesterday saying that “participate” in the launch of IPv6 beginning to implement the system. “The widespread availability of IPv6 access networks will Telefónica place throughout 2013 and beyond, depending on the projections of exhaustion of the IPv4 public address, different by region and countries where it operates, “the company said. That is, the process will be delayed considerably.

What sites are operating in IPv6?

Here is a complete list of the websites that are already operating in IPv6 . Universities, and companies like Google, Facebook, Bing, Cisco and others will begin to operate using IPv6 from now.

What do I have to do? Am I ready for IPv6?

The truth is that as a user of the network does not have to do anything. If you had problems last year to the day of IPv6 , you should register now no problems. Nearly all modern operating systems including Apple Mac OS X, Microsoft Windows, and much of the existing Linux distributions have integrated support for IPv6 for years.

What we might need is a router that supports IPv6 (if you have not already), but remember that if your ISP is not providing support to the new system will not help.
