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 ...

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, ...

In this article we cover one of what I have found to be the most common stumbling blocks for individuals attempting to pass the CCNA. This comes from experience in helping several individuals through ...

Subnet Mask divides the IP address into two segments and informs the computer which part is the network bit and which one is the host bit. For example, if there is an IP address: 192.168.0.1, it will ...

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 ...
