It would have been so easy if the early Internet and TCP/IP network designers had made IPv6 backward compatible with IPv4. They didn't. In 1981, IPv4's 32-bit 4.3 billion addresses look more than ...

Word around the net is that there's a new website technology that allows for a faster, safer web browsing experience, and it's called IPv6. As it turns out, this protocol isn't new at all, but instead ...

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 ...

In this post, I will explain some of the basics that are easy to understand. Before we discuss the differences between IPv4 and IPv6, we need to know some of the basics of IPv4. Finally, I will ...

Global Unicast Addressing, Routing, and Subnetting: This section introduces the concepts behind unicast IPv6 addresses, IPv6 routing, and subnetting using IPv6, all in comparison to IPv4. IPv6 ...

The move from IPv4 networking toward IPv6 networking is in full swing. As a result, networking equipment vendors are working hard to bring IPv6 support to their switch, router, and other networking ...

In a paper presented at the prestigious ACM SIGCOMM conference last week, researchers from the University of Michigan, the International Computer Science Institute, Arbor Networks, and Verisign Labs ...
