Homtide's Subnet Calculator allows you to quickly and accurately calculate the network subnets, IP ranges, and subnet masks based on your network address and subnet mask. This tool is essential for network administrators and IT professionals.
A subnet is a portion of a larger network, created by dividing the network into smaller segments. This allows more efficient use of IP addresses and better control of network traffic. A subnet mask defines how the IP addresses are divided into network and host portions.
| Subnet | Network Address | First Usable IP | Last Usable IP | Broadcast Address | Usable IPs |
|---|---|---|---|---|---|
| Subnet 1 | 192.168.1.0 | 192.168.1.1 | 192.168.1.254 | 192.168.1.255 | 254 |
The subnet mask used in the example is 255.255.255.0, which can also be written inCIDR notation as /24, meaning the first 24 bits are used for the network portion.
