Enter an IPv4 address and prefix (for example 192.168.1.0/24) to compute the network address, broadcast address, usable host range, netmask, and total addresses. Pure in-browser math.
A single IPv4 address with a prefix, written as 192.168.1.0/24. The prefix must be 0–32, and any host bits you type are masked off to the network boundary, so 192.168.1.50/24 is calculated as the 192.168.1.0/24 network.
No. This calculator handles IPv4 only — an IPv6 address or a prefix longer than 32 is rejected as invalid input. For IPv6 ranges you need a dedicated IPv6 calculator.
No. All the address math runs in your browser and nothing leaves your device. No network range you enter is transmitted or recorded.
