North America's supply of IPv4 addresses to dry up this summer

  1. North America is forecasted to run out of IPv4 addresses this summer. The American Registry for Internet Numbers (ARIN) notes that only 3.4 million of the 1.3 billion IP addresses assigned to the region remain available. Fortunately, there’s already a backup plan in place but it won’t exactly be cheap to make the switch.

    As The Wall Street Journal reminds us, those who created the Internet in the early 1980s created a finite amount of addresses – roughly 4.3 billion – as part of the IPv4 specification. While that may have seemed like a huge number back then, today’s Internet-driven world is proving otherwise.

    Running out of addresses won’t spell the end of the Internet but it’ll certainly be a hassle, especially for large companies like those that provide cloud computing services. The Journal points out that unprepared companies could incur unexpected costs, technical issues or even the inability to take on new customers.

    Large companies like Amazon, Salesforce and Microsoft have been snapping up IPv4 addresses by the hundreds of thousands, paying on average $11.25 per address. Others, like Facebook, have already made the switch to IPv6.

    Approved in 1998, IPv6 is the most recent version of the Internet Protocol. Whereas IPv4 uses 32-bit addresses to provide a maximum of 4.3 billion addresses, IPv6 addresses are 128 bits long which increase the number of available addresses to 340 undecillion (that’s the number 340 followed by 36 zeroes – enough to supply every atom on Earth with its own IP address).

    Sucks to be the ones that waited til the last minute. Even facebook figured it out early. That's pretty embarrassing, or proof this isn't a big deal. I mean... facebook!!!

    Home users won't be effected. Their routers will just translate IPv6 addresses to their computers when they connect to the Internet. But those servers sitting on the Internet will worry. New companies looking to establish a web presence will have some complications.

    LOL what is that even supposed to mean? Yeah I forgot Facebook is such an old company behind the times. It isn't like they revolutionized communication or something.../s

    If a social networking site can prepare itself, anyone can.

    Agreed. It's like Y2K all over again.

    facebook is not just a normal social network. it is a huge company that spans the entire globe with servers in every region of the world and with services that go well beyond just posting pictures and liking somebody.

    unfortunately large older companies tend to be very slow in switching technologies and smaller ones need to have a really good reason to do so because of the costs. it's how it has always been in cases like this.

    hopefully, the switch to IPv6 will happen sooner than later.

    Facebook has no valid reason either. Excuses, excuses.

    IPv6 was 8 years before facebook even came online. Should have had support for IPv6 since day 1. And it's been another 11 years since.

    A few years, fine. But not a decade plus.

    Especially with all the articles and topics the last few year talking about IPv4 drying up. This should be a non-issue, because of all the advanced warnings.
