Subnetting and creating subnet masks is often outsourced to consultants, but doing it yourself can be both challenging and rewarding. In the IT world, specifically in networking, there aren’t many ...

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 ...

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 ...

If computers in an open network talk freely with one another and two computers start talking at the same time, you have a “data collision.” Collisions may be arbitrated via Carrier Sense Multiple ...

When you set up the first network for a small business, you may not give much thought to how the company’s growth will affect your IP addressing scheme. By planning ahead at the beginning, you can ...

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 ...

In this next episode of NetworkChuck’s you SUCK at Subnetting course, we dive a bit deeper into how RFC1918 and NAT saved the internet from crumbling due to IP address exhaustion. So don’t miss out as ...

In the last two articles, we talked about IPv4 basics (Part IV) (Part V). We introduced the concept of folding a sheet of paper to understand subnetting. Each fold of the paper is a bit borrowed from ...
