If you have even a passing interest in the topic of IP addresses, then you should take a look at the following information. This strange and enlightening article presents some of the latest difficulties on the subject of IP addresses. IP Address stands for Internet Protocol Address and is currently made up of four “octets” or numbers separated by a period. Each octet can be a number from 0 to 255.
Well here`s a fun story because 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 recognize the IP address 22.214.171.124 as a server for fairfax.com.au, which publishes this newspaper online.
There are more than four billion combination’s. 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 dialed 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.
Here you can check your own IP adress :
Or you can download vTrace and use it from your own computer. vTrace combines traceroute, ping, whois, nslookup (dig), netstat into an easy to use graphical interface that analyzes Internet connections to quickly locate where an outage or slowdown occurs.
In addition, vTrace identifies the geographical location of IP addresses on a map. While many IP lookup tools only provide network provider locations, this module uses GeoIP location engine to provide a much higher level of accuracy by identifying the actual physical city and country location of servers and routers.
