Is official, there are no more IPv4 addresses!
Since I’ve first learned about IPs, I’ve wandered when will the possible number of addresses will run out. Now is official, there are no more IPv4 addresses!
ICANN (Internet Corporation for Assigned Names and Numbers) has officially announced on February 3 that the las IPv4 addresses have been allocated. Off course they haven’t been allocated directly to the users, but they will be used by ISPs.
But what will happen if there are no more IP addresses? Well, as this has become obvious some ware in the evolutionary process of the Internet IPv6 was created. What is the difference? Well, using IPv4 there are about 4 billion addresses, with IPv6 there are 3.4×1038, in fact I don’t even know how to pronounce a number that big, but it will be enough for a very long time.
Fortunately, a lot of operating systems already have support for IPv6, and if they don’t, they will start having very soon.
