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 ...

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 ...

A subnet mask is a number that specifies which parts of an IP address represent the host and network portions of the address. These masks are 32 bits in IPv4 networks and 128 bits in IPv6 networks. A ...

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 ...

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 ...

Subnetting is a fundamental part of network architecture and design. Network administrators create subnets to divide the network into smaller segments and gain granular control of the infrastructure.

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 ...

If you’re looking to segment a TCP/IP network, subnetting is not your only option. CIDR, or supernetting, is another way to accomplish the task and offers some unique solutions. Here’s how to use ...
