Due to the incorrect allocation management and the continuous increase of internet-capable devices, IPv4-adresses are nearly exhausted. For this reason and because of new requirements demanded by the technique of the internet the IPv6-protocol has been developed. The IPv6-protocol provides a larger adress space and will gradually replace the IPv4-protocol. However, the routing-protocols have to be adapted to the new internetprotocol. This paper will introduce and analyse the dynamic Routing-Information-Protocol RIPng which in itself is an inter-gateway protocol (IGP). The routers inside the network can exchange information about their different connections over this protocol. Furthermore, this paper will explain the basics of the IPv6-protocol, of the used protocol-algorithm as well as of the RIPv2-protocol. In the practical part of the paper the Counting-to-Infinity-Problem and some attributes of RIPng will be reviewed under the IPv6-protocol.
