America Runs Out of IPv4 Internet Addresses

Posted by samzenpus on from the empty-bucket dept.

FireFury03 writes: The BBC is reporting that the American Registry for Internet Numbers (ARIN) ran out of spare IP addresses yesterday. "Companies in North America should now accelerate their move to the latest version of the net's addressing system. Now Africa is the only region with any significant blocks of the older version 4 internet addresses available." A British networking company that supplies schools has done an analysis on how concerned IT managers should be. This comes almost exactly 3 years after Europe ran out.

    At this point, ISPs need to mandate that customers use SNI where possible; too many IP addresses are allocated just for an SSL certificate. I think we'll start seeing more Let's Encrypt-type Subject Alternate Name management tools, too.

      Agreed. If you aren't capable of using SNI, then chances are your server software, client, etc. are not fit to be on the Internet anyway.

      IE6, Firefox *1* (!), Chrome 4. If you're still using those, get something else immediately because your security of the certificate is then the LEAST of your worries.

      I'm waiting for the "Let's Encrypt" to start issuing certificates. When that happens, interesting things will happen in the SSL/TLS certificate market.

    The real WTF is that Slashdot has been running IPv6 articles for years...and *still* doesn't support IPv6.

    Facebook on the other hand - not a tech site, but a site for angsty teenagers, baby pics, cat memes and partisan squabbling - has supported IPv6 fully for years.

    It's embarrassing that a tech site can't do what a non-tech site has been doing for years.

    The problem with this is that some of the original recipients of those really big blocks like GM and HP were given those addresses, not leased them. They, for all practical purposes, own that address space.

    I know the organization I work for is a part of the problem. Before ARIN existed, a group of three schools (I work for one of them) were granted a /8 as a part of our research status. We have no relation with ARIN, and there isn't even a way to really give back 100 of the /16's we don't use.
