NAT and PAT are fundamental techniques in IPv4 networks. They enable efficient use of IPv4 addresses and offer advantages in terms of security and flexibility, as we will detail throughout this lecture.
IPv6 was introduced in the 1990s to address the limitations of IPv4 addressing, particularly by providing a larger address space to accommodate the exponential growth of the Internet and to introduce new features. However, IPv4 addressing remains widely used and continues to coexist with IPv6 on the current Internet. Both protocols can operate together, allowing for a gradual migration from IPv4 to IPv6 addresses.
Routing in networks involves finding the lowest-cost paths to forward data to their destinations. Routers act as guides, helping data reach its destination in the most efficient way possible. In this lecture, we will explore how this process works and how data is guided through computer networks.

The lesson introduces networks and then presents IPv4 addressing.
