Abstract
This thesis explains the differences between IPv4 and IPv6. Another important part of the thesis is to review the current readiness of IPv6 for worldwide production use. The status (in terms of readiness, adaptability, compatibility and co-existence) of IPv6 in TeliaSonera is discussed in more detail. The most important reason for migrating to IPv6 is the address exhaustion of IPv4. This may not be a big problem in the developed countries but in developing countries the growth of Internet is fast and lots of more addresses are needed. The need for addresses is not only from computers but from many devices connected to the Internet. Attempts to slow down the exhaustion of free addresses have been made but current solutions are not enough. IPv6 will solve the problem by using much longer addresses. It will also add security features and simplify headers to speed up routing. TeliaSonera has started to roll out IPv6 services. At the beginning the corporate customers will receive IPv6 connectivity and consumers will follow later. TeliaSonera International Carrier is already serving its customers with IPv6. It seems that IPv6 is ready, standards have been ready for years and support in devices and software is prevalent. To achieve and keep up the global connectivity, IPv6 is a must and should not be avoided.Description
