To understand how subnetting works, you first must have a good basic understanding of IP addresses. An IP address is set of binary octets broken into quads. That definition may not have made any sense ...

Linux networking is the backbone for servers, developers, and IT pros who need precise control over connectivity. From mastering IP addressing and subnetting to configuring interfaces and testing with ...

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 ...

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 ...

Broadcast and video production systems are moving rapidly into the IP realm. Therefore, understanding IP basics is now part of the engineer’s toolkit. To understand how IP works, we need to understand ...

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 ...

Table 1. This table illustrates subnet masks. The number after the “/” in the CIDR notation indicates the total number of IP addresses available. Click here to see an enlarged diagram. Understanding ...

Internet Protocol (IP) addresses take the form xxx.xxx.xxx.xxx, where xxx (an octet) is a number from zero through 255. There are public IP addresses and private IP addresses. Public IP addresses are ...

If you're looking to segment a TCP/IP network, subnetting is not your only option. CIDR, or supernetting, is another way to accomplish the task and offers some unique solutions. Here's how to use ...
