As such, in the ARIN service area, businesses will find it increasing hard to get IPv4 addresses.This announcement affects only North America, and other regions of the globe still have a reserve of IPv4 addresses at their disposal, with the biggest pool belonging to Africa. “On 24 September 2015, ARIN issued the final IPv4 addresses in its free pool”, wrote ARIN chief executive John Curran.

Many US network operators have been preparing for this day by transitioning to IPv6 and its virtually unlimited supply of addresses. In North America, the American Registry of Internet Numbers (ARIN) has been in control of doling out IP Addresses amongst the millions of people who live here. “While ARIN will continue to process IPv4 requests through its wait list and the existing transfer market, organizations should be prepared to help usher in the next phase of the Internet by deploying IPv6 as soon as possible”. While IPv4 was limited to just about 4 billion addresses, IPv6 will provide 340 undecillion addresss (a one followed by thirty-six zeroes).
The reason that there needs to be such a dramatic jump in the number of IP addresses in the near and distant future is that’s where IPv4 was oriented toward computers, phones, tablets, cars, TVs, watches, and fridges may now need them. If you’re on an IPv6 network, you can’t browse a site running on a web server that uses only IPv4-such as Wired’s site-without some sort of compatibility layer in between.
With IPv4 rapidly approaching exhaustion in Europe – even with the release of some stocks that had been held back by bodies such as the United Kingdom government – it is expected to become increasingly hard for the internet of things (IoT) to grow at its predicted rate, as each device requires a unique IP address. If someone wants to have access to IP address, he will have to settle for IPV6 numbers till old, unused IPV4 addresses have been returned to the organization. ICANN highlighted the IPv4 shortage a year ago when it was compelled to ship recovered addresses to one of the RIRs. Since that time, we’ve been hearing forecast after forecast predicting precisely when the bank of IPv4 addresses would dry up. It may be noted that more than 99.967 percent of IPv6 addresses are still available.
The telco will have to spend a substantial amount of time and money swapping out home routers, most of which are incapable of supporting IPv6.

The adoption rate for IPv6 has been quite fast but still only 21.31 percent users are IPv6 enabled in the US.
