Title: 4+4: IP address extension without IPv6
It is well known that the Internet is running out of IP addresses. Address exhaustion is the major driving force behind the development and deployment of IPv6. However, even though the specification has been around for several years and code ready to go in the routers, transition to an IPv6 world is not coming any time soon. In my presentation I will describe an alternative and more pragmatic approach to expanding the Internet address space without the need for IPv6. This proposal which I call "IP 4+4" directly addresses the short-falls that limit the roll out of IPv6. For example, IP 4+4 does not require changes to routers, uses NATs as transition tools and provides incentives for transition. The aim of my talk is not necessarily to argue against IPv6 or to advocate yet another next generation IP protocol, rather, I propose a "plan B" to failure of IPv6 deployment. If time permits I will give a demo of 4+4 on a local 4+4 testbed I've deployed in the COMET Lab. I'm currently doing wide area tests and will release the code in due course.
