Use our free Subnet Calculator to quickly determine network parameters for IPv4 addresses. Enter an IP address and either a subnet mask or a CIDR prefix to calculate the network address, broadcast address, usable host range, and more.Note: This tool currently supports IPv4 addresses only. IPv6 subnetting follows different principles and is not supported by this version. IP Address Enter an IPv4 address (e.g., 192.168.1.100). Specify Subnet By CIDR Prefix (e.g., /24) Subnet Mask (e.g., 255.255.255.0) CIDR Prefix CIDR Prefix Enter a number between 0 and 32 (e.g., 24 for /24). Subnet Mask Subnet Mask Enter the subnet mask (e.g., 255.255.255.0).Log in or register to post comments Comments
