IPv4 has 4.3 billion addresses, which may seem mindboggling. However, it took only two decades for it to reach its depletion. IPv6 has come to the rescue in the form of 128-bit addresses. Packet Tracer supports a wide array of IPv6 features. We'll start by learning how to assign IP addresses to different devices and how to configure routing between them. Finally, we'll create a setup that enables IPv6 communication over IPv4 devices.
