Don't Panic: IPv4 Addresses to Run Out in One Year

Ryan Whitwam

According to several people in the know, the Internet will run out of new IPv4 address space in less than a year . As more internet enabled devices flood the market place, we're moving inexorably towards the day when the new IPv6 standard will have to save the day. But will we be ready?

IPv4 addresses are limited to 32-bit numbers, thus about 4 billion unique addresses exist. The IPv6 standard uses 128-bit numbers. So that works out to a few quintillion addresses. That should certainly be enough to tide us over until we entrust our network infrastructure to the loving embrace of Skynet. Most of the hard work to get ready for the changeover needs to be done by ISPs, which need to deliver addresses as IPv6.

Large content providers like Google and Facebook aren't just sitting back though. They will need to work with ISPs to ensure their content is implemented as IPv6. Do you foresee any issues with the IPv6 transition?
