Övergången från IPv4 till IPv6 : varför dröjer den?

by Dongo, Daniel

In the near future everything from computers, cell-phones to cars will have established a connection to the Internet. This means that every single unit whom wishes to maintain a connection to the Internet will be required to have an unique IPadress to identify itself and the rest of the Internet. The current Internet in the form of IP version 4 (IPv4) is not capable of handling this because of the shortage of IPv4adresses. Furthermore the current Internet, despite its huge amount of users lack any form of built-in security while the demand of new services and technology from current users drastically grows. The new IP version 6 (IPv6) which has already been standardized upgrades the address-space which IPv4 holds and thus solves the problem of the shortage of IPv4-adresses. IPv6 also provides built-in security, new services and a number of technical advantages over IPv4. Despite the problems of the dated IPv4 which was created more than 20 years ago the transition to IPv6 proves difficult. The deployment of IPv6 varies from one geographical region to another. Organisations and users do not know when to expect IPv6 from the major Internet Service Providers (ISPs). This report aims at investigating what has been most significant for the ISPs not having deployed IPv6 in a larger scale than what has been done today. The result of the report could be used to get an insight in what needs to be changed so the deployment of IPv6 can be continued. Furthermore the report can give an insight in where in the transition the ISPs stand today.
