Example input/output

Input: IP: 192.168.1.100 / Mask: 255.255.255.0

Output: Network: 192.168.1.0 / Broadcast: 192.168.1.255 / Usable hosts: 192.168.1.1–192.168.1.254

How it works

This tool performs bitwise operations on the 32-bit representations of the IP address and subnet mask to compute the network address, broadcast address, and host range. It also identifies the network class. Processing runs in your browser.
