Main subject of this final paper is the Internet Protocol version 6 – how and due to what needs is was designed and created, what are the principles of its functioning and what new possibilities is it offering. To be able to talk about IPv6, we certainly have to mention its forerunner: the Internet Protocol version 4. Through short comparison of these two protocols we will explain the advantages of the version 6, but also mention the problems, which turned up during its implementation into the systems for the past 15 years. Because of its slow implementation the situation and progress is not in the same in every country, and we will compare the process in our country with neighbouring countries.

Glavna tema ovog završnog rada je Internet protokol verzija 6 (engl. IPv6 – Internet Protocol version 6) – kako i zbog kakvih potreba je nastao, koji su principi njegova funkcioniranja, te koje nam nove mogućnosti pruža. Naravno, da bi se moglo govoriti o IPv6 protokolu, svakako se mora spomenuti i njegov prethodnik, IPv4 protokol. Kroz kratku usporedbu tih dvaju protokola navest ćemo prednosti verzije 6, ali i spomenuti probleme oko njegove implementacije u sustave, koja traje već petnaestak godina. Budući je implementacija spora i ne odvija se istom brzinom u svim zemljama svijeta, dotaknut ćemo se i situacije koja se zbiva u našoj zemlji u odnosu na države koje nas okružuju.
