IPv6@HOME

摘要

This paper presents a practical approach to connecting a home network to the IPv6 world. A number of connection methods have been proposed and deployed, some suitable for a rich network environment, e.g. enterprise networks. Home networks are particularly significant due to the large number of sites. Home networks are connected via a wide variety of access technologies, e.g. xDSL, broadband, FTTH, however in general these all use IPv4 only. Due to the shortage of IPv4 addresses, and the way they are allocated to home users by service providers, there can be problems with traditional method of transitional IPv6 connectivity. For example, v4 addresses assigned are often changed frequently, whereas other providers use NAT and do not allocate global addresses at all. In this paper we examine those problems and suggest a possible method to connect a home IPv6 network by implementing existing transition mechanisms in the home gateway. We also propose an easy way to access all devices by interoperating with IPv6 Dynamic Domain Name Service (DDNSv6). The solution is simply and has a low implementation cost.
