INTERNET TO RUN OUT OF IP ADDRESSES 'IN 500 DAYS'

It has emerged that the IP addresses used in helping to distinguish one computer from another are expected to run out in approximately 500 days.
The unique numbers, which are known as Internet protocol addresses, help identify the world's networked devices.

An IP address uses four numbers from 0 to 255 to distinguish one computer from another. As an example, computers around the world can recognise the IP address 203.26.51.71 as a server for fairfax.com.au, which publishes this newspaper online.

There are more than four billion combinations. But the proliferation of networked devices means soon that will no longer be enough.
In a way, IP addresses are like phone numbers, which need to be entered correctly if a right connection is to be made. So the ability to uniquely identify everything in the computer world is essential.
IP addresses are like phone numbers in another way, too.

Just as Australia had to move from seven-digit phone numbers to eight digits in the early 1990s, massive change will now be required globally to resolve the problem.

However, there's a complication.

"Unlike the telephone system, it's not easy to just add more digits," the Sydney Morning Herald quoted chief scientist at the Asia Pacific Network Information Centre, Geoff Huston, as saying.
Although every telephone number in Australia was successfully altered, the phones themselves didn't change. Humans simply dialled an extra number and were connected to the person.
But every web server, every iPhone, every router and everything else - possibly billions of devices - will need to be reconfigured or upgraded.

"The idea that every last one has to go back into the doctor for a new transplant does sound a bit frightening. It's almost like having to teach every device a new language," Huston said.
Fortunately, a new language exists.
Computers now use IP version 4 and have since the 1980s. Its replacement is version 6, known as IPv6. For humans, little will change.

The traditional way we visit a website, by typing google.com or facebook.com, won't be any different and personal computers will automatically use IPv4 or IPv6 as required.

The impending shortage has been apparent for more than a decade as the volume of networked devices has escalated but inertia has stymied efforts to prepare for IPv6, Huston revealed.
While personal computers have been capable of understanding IPv6 since Windows XP and Apple OS X, Huston says only about 5 percent of devices are configured to do so. Among web servers, the figure is less than 1 per cent.
Internode is one of the few Internet service providers that offers an IPv6 service. Telstra is among the many that do not. Tens of millions of mobile phones are on an IPv4 network only.

Technically, it's not all that difficult to enable IPv6. Logistically, it's a horrendous challenge, and the conversion can involve substantial costs, with little in return.
"It doesn't make your Internet any shinier or any brighter, so customers won't pay more," he said.
Consequently, Huston predicts we will get to a point where large numbers of people will no longer be able to see everything on the Internet.

So far, the dwindling storehouse of IP addresses has been managed with trickery that translates one IP address to another.
But by about late September next year, the key body that distributes IP addresses will run out of them. Three months after that, every drop in the pipeline will dry up and the only way to get an IPv4 address will be to buy one from someone else.
Lacking that, consumers whose computers are not configured to use IPv6 won't see new websites. Likewise, iPhones, which don't understand IPv6, will be limited to the "old" Internet.

For businesses that are not prepared, this could spell trouble. Unless web servers and mobile phone services are configured to send information via IPv4 as well as IPv6, companies could be left with a fraction of their current customers.
The good news is that once IPv6 is in place, it should satisfy demand as far as a computer can calculate.
"If every single address was one grain of sand, in IPv6 you could build 300 million planets the size of Earth," he added.

500 HARI LAGI, INTERNET BERHENTI TUMBUH

Dalam kurun waktu 500 hari lagi, internet diperkirakan akan kehabisan alamat Internet Protocol (IP) --sederet nomor unik yang membantu mengidentifikasi semua perangkat berjaringan internet di seluruh dunia.

Alamat IP umumnya menggunakan kombinasi empat angka dari 0 sampai 255 untuk membedakan satu komputer dengan komputer lainnya. Saat ini, tercatat ada lebih dari empat miliar kombinasi angka untuk alamat IP.
Namun pertumbuhan pesat jumlah perangkat berjaringan internet akan membuat kombinasi empat angka tidak akan lagi cukup untuk membuat sebuah alamat IP. Inilah yang akan menjadi masalah di kemudian hari.

Peneliti dari Asia Pacific Network Information Centre di Australia Geoff Huston memberi gambaran bahwa alamat IP hampir sama dengan nomor telepon, di mana kita harus memasukkan nomor yang benar untuk menemukan koneksi yang dituju. Ketika semakin banyak pengguna telepon, diperlukan penambahan satu digit angka untuk sebuah nomor telepon. Namun tidak demikian halnya dengan alamat IP.

"Tidak seperti sistem telepon, tidak mudah hanya dengan menambahkan lebih banyak digit pada deretan angka alamat IP," kata Huston.
Konsekuensi dari masalah ini, menurut Huston, di kemudian hari akan ada banyak orang yang tidak bisa lagi melihat apapun di internet. Diperkirakan hal ini akan terjadi dalam waktu kurang lebih 500 hari lagi.

Jika itu terjadi, maka tak akan ada perangkat baru yang bisa terhubung ke internet, artinya internet akan berhenti tumbuh. Untungnya, dengan teknologi IPv6, 'kiamat' internet itu tak akan terjadi.
IPv6 merupakan sistem penomoran baru yang menggantikan sistem kombinasi empat angka yang sekarang digunakan. Bagi pengguna internet pada umumnya, perubahan dari sistem saat ini ke IPv6 tidak akan terasa.
