Summary
TCP/IP is a huge topic with hundreds of sideroads one can wander down and get lost on for a day or three. The facts remain: TCP/IP is the backbone of the Internet, routing is the glue that holds it all together, and IP addressing represents the places we visit as we surf the world. And when you think about it, given the explosive growth demands that the Internet in particular, and computing general have seen over the last three or four years, the infrastructure really is holding up remarkably well.
