The World Wide Web will run out of IP addresses in 2011
The unstoppable expansion of the internet might come to a halt in about three year's time.
According to calculations of the Organisation for Economic Co-Operation and Development (OECD) the address space of the currently used IPv4 protocol, which is containing about 4.3 billion IP addresses, will reach its limit at that time, if the growth keeps at its current pace.
This is the reason for the OECD to appeal to governments and industry for them to support the switch to the modern IPv6 protocol with campaigns and further education. This protocol was developed in 1995 and is able to deliver up to 350 sextillion IP addresses, but isn't widespread.
Japan is using it for earthquake research and China is considering a test run during the Olympic Games. At the moment there are only a few providers supporting the IPv6 protocol. The operating systems, which can deal with the protocol are Windows Vista, Mac OS X and Linux (upwards from version 2.4/2.6).
