Will the Web run out of address space?

The world could well run out of internet addresses next year, unless urgent action is taken to switch to a new generation of net addresses, the European Commission has warned.

According to the commission, businesses urgently need to upgrade to internet protocol version six or IPv6, a new version of the web’s addressing protocol, which will hugely increase the number of available addresses.

The IPv6 system has been ready for over a decade and is providing 340 trillion web addresses. But, not many companies are actually ready to migrate to the new platform.

A survey, conducted by the commission, found that few companies are prepared for the switch from the current naming protocol, IPv4, to the new regime, IPv6, the Daily Telegraph reported on Tuesday. The IPv4 and IPv6 protocols refer to the way in which addresses are created and assigned. Each website has a unique IP address, represented by a string of numbers, such as 192.168.1.1, which are then given a user-friendly web address to make them easier to remember.

The IPv4 protocol uses 32-bit addresses, which enables the web to support around 4.3 billion unique addresses while IPv6 uses 128-bit web addresses, creating billions of possible new web addresses. The EC survey found that of the 610 government, educational and other industry organisations questioned across Europe, the Middle East and Asia, just 17% have upgraded to IPv6.

Detlef Eckert, director in commission’s information society and media directorate-general, said: “Only by ensuring that all devices connected to the internet are compatible with IPv6 can we stay connected and safeguard sustainable growth of the internet.”
