The news is a few days ago The Internet Assigned Numbers Authority (IANA) (http://www.iana.org/), which has among its tasks delivery of IP addresses required for computers and all other electronic devices to connect to the Internet, will deliver the latest in recent days Groups yet to address some internet service provider in Asia and then all addresses will be officially delivered.
The numbers of internet protocol (IP) are the basis of the functioning of the Internet a bit 'as the phone number is the basis of the functioning of the global telephone system. The specification for IPv4 are about 30 years ago and are much more long-lived example of the specifications of the World Wide Web was born exactly 20 years ago. An IP number is currently 32 binary digits long commonly written as 4 decimal numbers between 1 and 255 as the my current number is such that 87.5.241.178, this allows the maximum to generate about 4.3 billion of numbers a huge number for that time but now, also because of many waste made in recent years, is tight. 's an example to understand the company HP (the computer) still holds all the addresses from 15.0.0.1 to something like 15,255,255,255 16,777,216 addresses (how did I know? Simple database is public and accessible at this address http://tools.whois.net/whoisbyip/ )
In fact, it seems, many U.S. companies and organizations that initially, when the shortage was not revealed, received a huge number of addresses that still lie largely unused to these realities will be asked to voluntarily return the unused portion and it will survive a few more months and then?
Then the internet will be forced to gradually move to a new version of the protocol addresses characterized by much larger (128 binary digits) that will allow to generate so many numbers that provide all that we do not need to change protocol . Wikipedia offers an author of the ratio between the number of available addresses and the surface of the Earth by way of comparison: we have with IPv4 addresses for approximately 9 square miles and with the new IPv6
we will have to address 667134515483770055 mm square. Enough?
The new numbers will be very strange because the old to write in a compact (so to speak) you will use the hexadecimal notation such an important service in the server already has this address 2001:07 fd: 0000:0000 : 0000:0000 : 0000:0001, to look better address blocks can be reduced to zero bits may be replaced by: that the address becomes 2001:7 fd:: 1 more little resemblance to a number, but at least a reasonable size.
What problems will meet as Internet users, at least not many users of our computers if we are not just old and run Windows 2000/XP on or from any version of unix including MacOSX are already compatible, so all phones smartfone that connect to the Internet, the devices that might not be network devices are mainly small router that we use at home they must receive a new firmware be replaced with new or newer equipment. The most significant costs will be borne by the companies that manage Internet protocol that will have to adapt to the new management of all devices.
Siete curiosi? Se si potete provare la nuova internet a partire da questo indirizzo http://gogo6.com/ non è una cosa semplice ma dopo esservi registrati potete scaricare un piccolo programma capace di collegarvi ad una rete IPv6 di test con una tecnica simile a quella delle VPN. Effetti? Consultare google così:
