In order for internetworking to work, there has to be a way to distinguish which network a device belongs to. This is accomplished with a form of addressing called logical addressing, which is represented by an IP address. In this course, we will follow the evolution of IP addressing from classful addressing through class-less addressing. Along the way, you'll learn how network masking operates. You'll also be able to describe network address translation, and you'll learn the value of variable length subnet masking.
