网络掩码计算器

网络掩码计算器

Calculate subnet details from any IP address and CIDR notation or subnet mask. Get network address, broadcast address, usable IP range, wildcard mask, and binary representations — instantly in your browser.

如何使用

Enter an IP address with CIDR notation (e.g., 192.168.1.0/24) or a subnet mask. Results calculate in real time as you type, showing all network details. Use the cheat sheet tab for a quick reference of all CIDR notations, or batch mode to calculate multiple subnets at once.
