IPv6 Transition Technologies

Today, the Internet (and the world) is mostly running on IPv4 networks. As more and more operating system and devices natively support IPv6, and even require it, making IPv6 work globally will quickly become necessary. Because IPv4 and IPv6 devices cannot natively communicate with one another, protocols have been developed to bridge the gap, and these are known as the IPv6 transition technologies.

Before discussing transition technologies, or how we can make IPv6 devices communicate with IPv4 devices, we need to examine the different types of nodes on the networks, as defined in RFC 2893:

IPv4-only node—This type of nodes uses IPv4 only and most likely does not even have the IPv6 protocol installed. This is Windows ...
