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 ...

We have recently spoken about IP routing, but there is something else that needs our attention, and it is all about the types of routes found in a routers routing table. It might sound confusing but ...

Welcome! Throughout this course, Network Systems Foundations, you will delve into the fundamental layers of network communication. You will start with a thorough discussion of the Link Layer and its ...

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 ...

Folks need to understand what IP routing is when it comes to networking. But not only that, they should also be familiar with the various IP routing protocols. This article will explain everything ...

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 ...

Rather than layering security onto networks, the networks themselves and carefully managed authorization policies can hinder attacks, but at an administrative cost. Why is it that over 90% of ...

The third layer of the OSI Model, the network layer, is where most network engineers focus their time and expertise. As Darragh commented in my post on the data link layer, Layer 2 is cool but Layer 3 ...
