Understanding IPv4 and IPv6 Addressing

Each device connected to a network needs a logical address to be able to communicate with other devices and share resources. Without logical addressing, a sender will not be able to specify the delivery address or location for a message, and a recipient of a message will not know the sender’s address if a response is needed. Within private networks within organizations and public networks on the internet, each device is assigned a logical address, which helps networking devices forward messages between a source and a destination.

In this chapter, you will understand the need for public and private IP address spaces and why it matters to networking professionals and organizations. You will gain a solid foundation in understanding the various types of IPv4 and IPv6 addresses, and why these address types are needed on networks. Lastly, you will explore IPv6 concepts and learn how to configure IP addresses on various devices.
