How to Calculate IP Subnet
What is IP Subnet?
An IP subnet calculator determines network address, broadcast address, usable host range, and total hosts from an IP address and CIDR notation (e.g. 192.168.1.0/24).
Formula
- n
- first n bits are network — first n bits are network
Step-by-Step Guide
- 1CIDR /n = first n bits are network, rest are host bits
- 2/24 = 256 total addresses (254 usable)
- 3Subnet mask: /24 = 255.255.255.0
- 4Usable hosts = 2^(32−n) − 2
