It seems that there are no more IPv4 available addresses for the Northern America, as the American Registry for Internet Numbers (also known as ARIN) said that the company has given the last IPv4 addresses in its free pool.
This was something expected, as ARIN has warned us for years that the IPv4 addresses were running out. In May 2015, ARIN confirmed that, most likely, before the summer of 2015 we’ll run out of IPv4 addresses.
Vint Cerf, the president of ARIN, said that 40 years ago, when they’ve “designed” the internet, they’ve made some calculations and estimated that 4.3 billion terminations should be enough for an experiment.
If you don’t know what IP addresses are, then we will tell you that they are the numerical identifiers given to the hardware of computers, ranging from enterprise servers or personal desktop computers.
The IPv4 protocol was released back in 1981 and can only hold a maximum of 4.3 billion unique addresses. However, there is a new protocol named IPv6, which is waiting to be adopted by enterprises and carriers. The IPv6 protocol was released in 1999 and can hold up to 340 undecillion addresses. If you don’t know how much is that, then just consider putting 36 zeroes after 340 and you will get the exact number that we’re talking about.
In concordance with ARIN, this would be enough to serve the internet users for several generations. The users and businesses that would still want to use IPv4 addresses could just send in their requests to ARIN. However, the organization will need to wait until the Internet Assigned Numbers Authority (IANA) will give them some or when the users will be able to return some addresses that they no longer use.
We remind you that the IPv4 addresses can be purchased on so-called transfer markets, where you need to pay 10-12 dollars for one. However, as the IPv4 addresses are wasted in the Northern America, ARIN had to change the rules for the transfer approval that will eliminate the restrictions on how often the owners of an IPv4 address can transfer it to other users. With other words, the users and organizations could purchase previous owned IPv4 addresses instead of migrating to the IPv6, because the move will surely involve some costs.
What are your thoughts about the IPv6 addresses? Do you think that the IPv6 protocol will be introduced soon enough?
