A thesis work about planning and implementation of an IPv6 infrastructure brings a lot of novelty to an electrical engineering student, who is interested in computer networks and operating systems.

The Internet-Boom, the drastic increase in the number of the internet capable devices led to the depletion of the public IPv4 addresses. The new version of the Internet Protocol (IPv6) solves the problem of the IP address depletion, so in the future IPv6 will likely exchange the old IPv4. The transition can not take place momently. Every system administrator, who is thinking about the transition, need to get familiar with the most common transitioning techniques, options and methods, in order to find the best fitting solution to the given network.

First of all it is necessary to review the transition techniques chronologically, and examine the methods, that are delaying the transition from IPv4 to IPv6. These methods try to solve the depletion of the public IP addresses with the usage of private addresses. These ancient techniques are well-known, but it is essential shortly to demonstrate them.

The methods, that are supporting the IPv6 introduction and the coexistence of the two protocols, represent the present state. From user perspective, end user and service provider solutions need to be distinguished. From thechnical view, dual stack is the basic option, but the tunneling (embedding packages and forwarding them in a tunnel) and transitioning (address- and protocoltranslation) techniques need to be distinguished as well, that require dual stack device at least at the endpoint of the network.

The techniques, that are helping the return to the old techniques, are representing the future, as their importance will grow after the transition. It is necessary to prepare for the usage of these thechniques also.

The options and possible solutions of the transition in Hungary from IPv4 to IPv6, can be investigated through concret examples, the practical implementation can discover new findings, which can not be found in the literature.

After getting familiar with most important transition techniques it is possible to choose the best transition option on the network of the BME Department of Automation and Applied Informatics.
