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 ...

IPv6 is a powerful enhancement to IPv4 with features that better suit current and foreseeable network demands, including the following: IPv6 increases the number of address bits by a factor of 4, from ...

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 ...

Like it or lump it, you're going to need to add IPv6 to your network. Here's how to start. Some people still think they don’t need to worry about the growing shortage of Internet IPv4 addresses and ...

Although IPv6 adoption seems to be moving at a snail's pace, there's no outrunning it. Brien Posey demystifies some of the addressing issues many admins are still trying to figure out. [Editor’s note: ...

IPv6 is the successor to our current internet protocol, IPv4. It offers many new features, including a vastly increased address space (128 bits of address vs. IPv4's measly 32 bits), easier ...

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 ...

In the early 1990s, internet engineers sounded the alarm: the pool of numeric addresses that identify every device online was not infinite. IPv4, the fourth version of the Internet Protocol, used ...

Supernetting was created as a way to solve the problem of routing tables growing beyond our current ability to manage the exhaustion of Class B network address space. Much like one area code ...

Twenty years ago, the fastest Internet backbone links were 1.5Mbps. Today we argue whether that’s a fast enough minimum to connect home users. In 1993, 1.3 million machines were connected to the ...
