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 ...

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 ...

An IPv6 address is a 128-bit alphanumeric value that identifies an endpoint device in an Internet Protocol Version 6 (IPv6) network. IPv6 is the successor to a previous addressing infrastructure, IPv4 ...

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 ...

Thomas Edison, in 1882, opened a power station on Pearl Street in New York city to supply the densely populated Manhattan island with DC power [1]. DC was the logical power distribution standard at ...

Today, the standard methods for moving the network/host address boundary are variable-length subnet masking (VLSM) for host addressing and routing inside a routing domain, and classless interdomain ...

This is the first of many technical blog posts I’m going to post on IPv6 architecture and implementation for a Microsoft Windows-based environment. I started off with a basic introduction of the IPv4 ...

Many enterprises use OSPF version 2 for their internal IPv4 routing protocol. OSPF has gone through changes over the years and the protocol has been adapted to work with IPv6. As organizations start ...

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 ...

Enterprise networks that run on IP version 4, or IPv4, could be missing out on the enhancements found in IPv6. While a transition from IPv4 to IPv6 takes time and effort, organizations can evaluate a ...

HI! I'm Elliot Alexander, a London-based Computer Scientist with a background in software engineering. I've worked across the security and high-performance computing space, and am experienced in all ...

If you are using Internet or almost any computer network you will likely using IPv4 packets. IPv4 uses 32-bit source and destination address fields. We are actually running out of addresses but have ...
