Well this is the view being put out there by the man dubbed “the godfather of the internet” and vice-president at Google, Vint Cerf. In addition to stating that the shortage of internet address space in Europe represented a “serious boundary,” he went on to add that it’s one of the “biggest set of changes in the history of the internet.”
The problem comes down to the amount of space there is in Europe for IP addresses on IPv4. This has 4 billion addresses but only has 4% left which is expected to run out next year. The solution is IPv6 which has “340 trillion trillion trillion” addresses, however, not enough companies have taken this up as of yet.
