Description

The shortage of IPv4 addresses makes the need to migrate to IPv6 inevitable. This migration cannot be carried out in one piece, the coexistence of the two worlds is bound to continue. At the end of this internship, you will have learned the different migration mechanisms available as well as their fields of application.

Who is this training for ?

For whom ?

Engineers, network architects.

Prerequisites

Training objectives

Know how to implement a successful transition to IPv6 using proven techniques
