The last editionof this column discussed subnet masks and the nature of IP addressing. In this and the following column, we will begin discussing what subnetting means and how to do it. First, though, ...

Have you learned to think and dream in hex yet? That is what you are going to have to look forward to as we transition to using IPv6. Because we will be working in hexadecimal numbers we may need a ...

We just saw that the mask determines where the boundary between the network and host portions of the IP address lies. This boundary is important: If it is set too far to the right, there are lots of ...

In this chapter, you will learn about the addressing used in IPv4 and IPv6. We'll assign addresses of both types to various interfaces on the hosts and routers of the Illustrated Network. We'll ...
