Every device that uses the Internet requires an IP address. These addresses are number combinations that uniquely identify each device so that traffic can be routed to it. Until now IP addresses have been in the IPv4 format. Dating back to the 1970s, this format was designed to handle a maximum of 4 billion addresses, a gigantic number at the time. Meanwhile most of these addresses have been used up, thus the reason for the launch of the new World IPv6 standard.
From 6 June 2012 onwards, Google, Facebook, Microsoft, Cisco and other Internet providers will be permanently reachable via IPv6. IPv6 will then be usable for the wider public. Swisscom is also involved in the launch: the addresses swisscom.ch and swisscom.com can be accessed via IPv6. Swisscom has applied for certification as an IPv6-enabled Internet provider because the company meets the condition that a certain percentage of Internet traffic will be transmitted via IPv6.
