For one to be able to create multiple logical networks within a Class A, B, or C network, one needs to know the principle of subnet. Without using subnets, one could only use a single network no ...

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 ...

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 last edition of this column talked about subnets and introduced folding paper as an illustration of how subnets can be understood. This will be very useful as we proceed. MORE IPv4 SUBNETTING ...

I have a networking situation where some tools can or can't communicate between two devices on the same LAN but differing subnet masks (it's an error, will be corrected). The question is why do some ...

I feel stupid asking this, but I have always had a hard time understanding subnets no matter how much I have read on them. I always end up more confused than when I started.<BR><BR>What I do ...

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 ...

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 ...

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 ...
