The Internet Just Ran Out of Numbers

by

The MIT “Technology Review” has an interesting article all about IPv4 finally running out of numbers, and what to expect next now that this has happened. here are some highlights from it …

Every available Internet protocol address has now been spoken for—which could mean huge trouble down the line.

But there are now seven billion people on Earth, and more and more of them—and their devices—are going online all the time. Fortunately, engineers realized the limitations of IPv4 a long time ago and lined up a successor, called IPv6, in 1998.

And having relied on the same system for as long as 30 years, they may not feel the need to change.
