A subnet allows the flow of network traffic between hosts to be segregated based on a network configuration. By organizing hosts into logical groups, subnetting can improve network security and ...

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 ...

Before we can go into a detailed discussion of how to calculate the number of network hosts on a network, it is important to have a satisfactory level of understanding about where the whole concept of ...

The bits in the mask identify both hosts and subnets. The more hosts, the fewer subnets; the more subnets, the fewer hosts can be individually addressed. These bits become a tradeoff based on the ...

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 ...

Subnets are used for many AWS tasks (like creating an EC2 VM), so Brien Posey sheds some light on common errors to end some of the frustration around subnetting. There are any number of tasks within ...

The last editionof this column discussed subnet masks and the nature of IP addressing. In this and the following column, we will begin discussing what subnetting means and how to do it. First, though, ...

My book I'am reading IP fundamentals has gotten a bit confusing when getting combining several subnets which uses more bits for it's subnet number into one single subnet such as combining four /24 ...

One of the most prevalent problems with IP networks occurs when IP subnet masks are incorrect. This seems to happen frequently because the concept of the subnet mask is not understood accurately. In ...
