What is an IP Subnet?
An IP subnet is a smaller part of a larger IP network. Subnetting is the process of dividing a network into multiple subnets. Every subnet is defined by two things: an IP address and a subnet mask.
A step-by-step guide on how to use the MathCalc IP Subnet Calculator
- Enter an IP address in the first box.
- Choose a subnet mask from /24 (255.255.255.0), /25 (255.255.255.128), /26 (255.255.255.192), /27 (255.255.255.224), /28 (255.255.255.240), /29 (255.255.255.248), /30 (255.255.255.252).
- After entering the values, click on “calculate”, and in seconds, you will see the result.
Examples
Example 1
Enter IP address 192.168.1.0 in the first box. Choose /24 (255.255.255.0) from the subnet mask options, and you can imagine the result will appear in seconds.

FAQ
Define what an IP subnet is?
An IP subnet is a smaller portion of an IP network that is broader in scope. The IP address and the subnet mask are the components that define it. Together, they are responsible for determining the network address, the host range, and the broadcast address.
A subnet mask is what exactly?
By using a subnet mask, the Internet Protocol (IP) address is divided into two distinct parts: the network portion and the host portion.
