IPv4 to IPv6 translators
- [Instructor] There are some nifty tricks for performing translation of IPv4 addresses when these systems need to communicate into an IPv6 only network. Now I know, I know. There's not a lot of IPv6 only networks out there, but there's certainly going to be more and more of those as time goes on. One trick is the use of the well-known IPv6 prefix of 64:ff9b, and notice this is a /96 mask. The translation scheme makes use of a specialized address format called an IPv4 embedded IPv6 address. This type of address contains an IPv4 address inside of the IPv6 address. It can be encoded using one of six different formats based on the length of the IPv6 prefix, which is required to be either 32, 40, 48, 56, 64, or 96. An example would be 64:ff9b::198.51.100.16. Notice it is so great how the IPv6 address can carry embedded right inside of it the appropriate IPv4 address.
