Do You Know About IPv6...???

IP version 4 out! Once a title that decorate many news channels. Last February, IANA (the institution that regulates the use of IP throughout the world) does not hold anymore IPv4 addresses. All slots have already been distributed to the entire world through the coordinator of each continent. If the slots in each continent coordinator also gone, meaning the IPv4 officially sold out. Does this mean "doomsday" for the world internet? Actually, not really. Since 1999, has formed a forum in charge of making a new standard called IP version 6 (IPv6). When IPv4 runs out, we just move to IPv6. Just because the "move" is the entire infrastructure of the Internet, the process is fairly complicated and requires funding not less. But for a better future, we all had to move to IPv6. Even to encourage the movement, tomorrow will be held on IPv6. For those of you who still do not understand the question, here's a bit of explanation about the Internet Protocol as well as the advantages offered by IPv6.

What is Internet Protocol?
Internet Protocol (IP) is the standard that governs how and through which packets of information sent from the Internet or intranet networks. In order for data packets to the correct destination, each device connected to the Internet must have an IP address (IP Address) is unique. If two devices have the same IP, there will be a so-called "IP Conflict" will be confused because the packet will lead to nowhere.
What is the problem of IPv4?
When created in 1981, IP version 4 using 32-bit address, or "only" about 232 (4.3 billion) addresses. Of that amount, about 18 million addresses used for private network and 270 million for the multicast adresses, so it can not be used for the public. Actually, the remaining amount is still very much, but many more devices connected to the internet. As a result, the allocation of IPv4 addresses which have been not sufficient anymore. That's why we need IP version 6, which has more addresses.

When IPv4 addresses will be Out?
Depending on the area, but at least 1 to 3 years. The fuss caused yesterday more APNIC (the organization that regulates the use of IP in Asia Pacific) has requested an additional two blocks to the IANA IP Address (which regulates the use of the IP world). That request led to block IP addresses remaining 5 (one block has 16.8 million addresses). By law, if the IP block remaining five, it must direct the board is divided into 5 IP on every continent.

IP Address How long it will run out depending on the rate of Internet use on the continent. Continents with the fast pace of Internet usage, such as Asia Pacific or North America may be able to spend the remaining blocks within a year. But for the continent's internet penetration is widespread such as Europe, or the penetration of internet is still slow as Africa and Latin America, the remaining time can be annual.

IPv4 is completely discharged?
Actually there are still some out there that blocks unused. In fact, according to John Heideman, researchers from the University of Southern California, the use of IPv4 in fact only 14%. But rather difficult to pull back the IP address that had already spread. The source of the problem occurs early development of the internet, when purchases only IPv4 addresses are divided in 3 blocks: / 8 (16.7 million addresses), / 16 (65 thousand addresses), and / 24 (256). For companies or universities that require (eg) 67 thousand IP addresses, they get a block / 8 number of 16.7 million addresses.

Some parties such as Stanford University or the U.S. Defense Department has volunteered to return the IP address that is not their use. But there are still many parties such as MIT, IBM, Apple, AT & T, or Ford Motor is yet to determine her attitude. ARIN party could have asked them to restore the ration it, but considering the population that is now limited IPv4, IPv4 owner could have it as a valuable asset. Even the news lately sticking some parties still have IPv4 blocks sell at high prices.
IPv6 addresses can overcome these limitations?  
Yeah, because addressing capacity is up from 32-bit to 128-bits (2128) or exactly 340,282,366,920,938,463,463,374,607,431,768,211,456 IP address. In the future address as much as it may also be exhausted, but at least the situation was under control until hundreds of years from now.
IPv6 pengalamatannya own system using eight groups separated kuartadesimal colons. This is different from IPv4 addressing system that uses four groups of tridesimal.

Very Different?
Yes. In the name of difference, the technology was different. That is why the two protocols are not mutually compatible. Computers that are air-IPv4 can not find the mail server had an IPv6, and vice versa.

But that does not mean the internet will be jammed. Packages are packed in IPv6 systems can be repackaged into IPv4 packets so that data communication can still occur. But this way is certainly inconvenient and wasteful of resources, thus potentially lowering internet speeds significantly. Therefore, the best way is everyone moving to IPv6.

Okay, I'll migrate to IPv6. How do I?
To adopt IPv6, the required hardware and software support. On the end-product alias devices we use everyday, relatively no problem. The majority of the network card inside the computer, notebook, or smartphone today has IPv6 support. Similarly, the software side. Generation of Windows since XP Service Pack 1 already supports IPv6, as well as Mac OS X version 10.2 and all Linux distributions.

However, problems began to elaborate when it hits the Internet access device, such as your modem. The majority of the given modem Internet service providers do not support IPv6, so it must be replaced or upgraded. On the backbone, the problem is more complicated again. Servers, routers, load-balancer, and all nodes must be replaced in order to support IPv6.

So the core problem at hand rather than ordinary users, but on the infrastructure side. Because the amount of effort and investment that must be removed, this migration process can take place yearly.

So, the industry is not ready?
Ready not ready, we have to move. Some countries like the United States, Canada, France, Japan, China, and South Korea also has made a number of policies to accelerate IPv6 migration.

And on June 8, 2011 tomorrow, IPv6 Day is held worldwide. Agenda magnitude is testing IPv6 for 24 hours. Companies participating include Google, Facebook, Yahoo, Akamai and Limelight Networks. Hopefully, this step can encourage the industry to migrate to IPv6.
