IPv6: It works the same, it looks the same, it smells the same, it just has a lot more addresses 

Although most people in the room had heard of IPv6, only a few are actually using it. Marco Hogewoning, External Relations Officer and Technical Adviser at RIPE NCC, looked at the benefits of IPv6 and the delays in its implementation. IPv6 has 128-bit addresses, as opposed to IPv4’s 32-bit addresses, which means there is no need for users or devices to share IP addresses. Although the plan was to implement IPv6 alongside IPv4 and then gradually phase IPv4 out, take up has been very slow (e.g. UK 7%, Brazil 11%, Germany 22.2%, US 30%).
