# What Is A 25 Subnet?

## What does 25 mean in IP address?

/25 is the CIDR notation, which indicates a subnet mask of 255.255.255.128.

So, this means that 10.15.92.0/25 represents the network “10.15.92.0” with a subnet mask of 255.255.255.128.

The IP address range is from 10.15.92.1 to 10.15.92.126.

The network ID is 10.15.92.0.
