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 ...

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 ...

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 ...

Table 1. This table illustrates subnet masks. The number after the “/” in the CIDR notation indicates the total number of IP addresses available. Click here to see an enlarged diagram. Understanding ...

When you purchase through links on our site, we may earn an affiliate commission. Here’s how it works. One of the most prevalent problems with IP networks occurs when IP subnet masks are incorrect.

To connect some copiers or multi-function printers to a router, you may need to know the subnet mask value for the network. A subnet mask defines the value range of IP addresses used in a workgroup.

Is there an easy way (like via a .Net library) that allows me to get the IP address and subnet mask of the local machine that the application is running on?

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 ...

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 ...

The following summarizes how networks, subnetworks and hosts are identified in the TCP/IP protocol. An IP address is first divided between networks and hosts. The host bits are further divided between ...
