Class A subnet masks must start with 255.0.0.0 at a minimum, because the whole first octet of an IP address (the IP address describes the specific location on the network) is used to define 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 ...

George Ou explains IP subnetting using his own graphical approach. It's a great primer for students and a nice refresher for others. IP subnetting is a fundamental subject that’s critical for any IP ...

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 ...

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 ...
