The Internet will run out of Internet addresses in about 1 year's time, we were told today by John Curran, President and CEO of the American Registry for Internet Numbers (ARIN). The same thing was also stated recently by Vint Cerf, Google's Chief Internet Evangelist.

The main reason for the concern? There's an explosion of data about to happen to the Web - thanks largely to sensor data, smart grids, RFID and other Internet of Things data. Other reasons include the increase in mobile devices connecting to the Internet and the annual growth in user-generated content on the Web.

Why a New Internet Protocol is Needed

Currently the Web largely uses IPv4, Internet Protocol version 4. Each IPv4 address is limited to a 32-bit number, which means there are a maximum of just over 4 billion unique addresses. IPv6 is the next generation Internet Protocol and uses a 128-bit address, so it supports a vastly larger number of unique addresses. Enough, in fact, to give every person on the planet over 4 billion addresses!

John Curran from ARIN, the non-profit responsible for managing the distribution of Internet addresses in the North American region, told ReadWriteWeb that of the approximately 4 billion IPv4 addresses available, all but 6% have already been allocated. Curran expects the final 6% to be allocated over the coming year.

This is largely an issue that ISP (Internet Service Providers) and telecoms carriers need to deal with. However content service providers, including large-scale Internet companies like Google and Facebook, also need to ensure that the transition from IPv4 to IPv6 takes place. Curran explained that a content company like Google (for example its YouTube operation) will need to work with its ISP to transport the content via IPv6 as well as IPv4.

This transition is happening "slowly," says Curran. But he warns that "deployment is where we're behind."

Google, Facebook & Others Making Good Progress

John Curran told us that large carriers like Verizon and Comcast have announced trial IPv6 activity. Curran also noted that new Internet of Things initiatives that use sensor networks, power grids, RFID and similar technologies, are being directed to use IPv6 and not IPv4.

There is also solid support from the big Internet companies. Curran said that Google has already put the majority of its services onto IPv6. Declaring its support for IPv6 on a special webpage, Google states that "IPv6 is essential to the continued health and openness of the Internet [and] will enable innovation and allow the Internet's continued growth."

In June, Google held a Google IPv6 Implementors Conference. At that event, Facebook announced that it had begun to use IPv6.

In his opening remarks to the conference, Google's Chief Internet Evangelist Vint Cerf urges ISPs to move to IPv6, so that a "black market" for Internet addresses won't occur.

Another Y2K?

Critics view some of the push for IPv6 as Chicken Little 'the sky is falling' talk. Commented @ajbraun, a self-described technology leader at Sony Ericsson, via Twitter: "We should call this "IPv6: Y2K II." An obvious issue for 10 years, we will panic at the end and finally much ado about nothing."

Others see a technology called NAT (Network Address Translation) as a solution - it maps multiple addresses to a single IP address, thus reducing the amount of unique IP addresses required. However this is at best a temporary solution. Google argued back in 2008 that NAT and similar technologies "complicate the Internet's architecture, pose barriers to the development of new applications, and run contrary to network openness principles."

Whether or not there is Y2K-style fear mongering, the bottom line is that IPv6 is a much larger platform for the coming Internet of Things. So one way or another, the move will have to be made.

IP6 standard postoji jos od 1998. godine...
problem je sto ISP ne zele jos uvek da daju pare za tu opremu i da polako krenu u migraciju...
 
Ништа чудно. IPv4 има 32-битну адресу, што значи да имамо само отприлике 2^32 различитих адреса. Када је IPv4 стандард био у процесу осмишљавања, погрешно су проценили потребе тржишта за IP адресама, које је експлдирало после 2000те.
Стандард IPv6 је већ спремљен и само чека тренутак када ће заменити IPv4, тако да без бриге.

Nije problem u ISP. Do skoro je bio problem sto proizvodjaci mrezne opreme nisu hteli da implementiraju IPv6, odnosno cinili su to veoma sporo.
 
To je istina.
Srećom postoje rešenja za koegzistiranje IPv4 i IPv6 u prelaznom periodu, a Win7 recimo po default-u ima instaliran i IPv6 protokol.
Ovo je dobar razlog za masovniji prelazak na IPv6.
 
A i da ne predju na IPv6 na vreme... uvek mogu da oslobode IPv5 za narodne mase, već godinama ga koristi samo odabrana manjina kao Holivud i američke vladine agencije (CSI, Alias etc..).
 
Bio sam skoro na RIPE-ovom seminaru. Adrese koje narod koristi su 1/3 svih adresa, skoro 2/3 drzi americka vojska. I ostatak raznorazne organizacije kojima su davno podeljene adrese iz pitaj Boga kog razloga. I to isto veoma ozbiljni opsezi.

Ako se dobro sve iskombinuje radice IPv4 jos par godina sigurno, a ako se predje na IPv6 tada ce svaki korisnik imati ne znam tacno koliko puta vise adresa nego sto je imao kompletan IPv4.
 
ipv6 ima dovoljno adresa da obezbedi svakom stanovniku planete adresa koliko ima dlaka na glavi.
 
Nije problem to sto se koriste IP adrese vec to sto se neki opsezi ne koriste.
Kada je pocela podela javnih IP adresa ameri su naravno prvo sebi davali i to vrlo sirokogrudo.
Velike kompanijama , drzavnim institucijama pa cak i fakultetima i studentskim kampusima su davali /8 subnet od 16,7m IP adresa. Naravno delimicno treba zahvaliti i pocetnoj podeli IP adresa po klasama. I tako dok oni lepo izdelili opseg iz klase A shvatilo se da iz preostalog opsega IP adresa nece biti moguce podmiriti potrebe ostatka sveta pa se krenulo u osmisljavanje novog standarda IPv6 a u medjuvremenu je izbacen classfull podela IP adresa kao i uvodjenje privatnih opsega i NAT-a.
Verujem kada bi se sada izvrsili ponovna raspodela IP adresa da bi smo bili mirni jos duzi niz godina ali posto je IPv6 u svakom pogledu (ne samo u broju IP adresa koji nudi i koji predstavlja mozda najmanje bitnu stavku) superioran u odnosu na IPv4 to treba sto pre preci na noviji.
Inace kazu da ce uvodjenjem IPv6 standarda na svakog stanovnika planete doci oko 5*10^28 IPv6 adresa.
 
Sve je to teoretski... posto i sada ima puno adresa, ali nisu dostupne. Verujem da ce i u ovom slucaju biti velikodusni pa u stvarnosti broj javno dostupnih adresa biti manji...
 
Nema tu javno dostupnih adresa kod IPv6. Svaki uređaj automatski dobija svoju adresu, nema više podele kao kod IPv4.
 
to je ok... istina ja tu vidim problem, al ajd.
