How IP Addresses Work | Network Fundamentals Part 4

Welcome to the fourth part of the Network Foundation series. This video looks at IP addressing, and how it works. This is critical information for anyone new to networking, or studying for CCNA or CCENT exams. We start at the beginning, with what IP’s look like, and why. Understanding binary is your friend here! (). Did you know that IP addresses are two addresses in one? Yes, it’s true! An IP includes the host address, as well as the address of the network it resides in. Speaking of networks, we have changed how we address them over time. One of the early methods was to use classes. Perhaps you’ve heard of class A, B, and C networks? But this has its limitations. So, we also have classless networks, or CIDR (Classless Inter-Domain Routing). This introduces a new concept: The subnet mask. Now we can break up networks as we see fit! The next video will take this further, as we look at IP Addresses in Depth. The CCENT/CCNA study g
