Subnet Calculator
Subnet Calculator is used to divide an IP network into subnetworks by calculating network address, subnet mask, broadcast address and host IP address range. Please use the form below to enter an IP address and Subnet Mask, and we'll provide you with necessary information you'll need.
Enter a IPv4 or IPv6 and CIDR (IP/CIDR):
Example IPv4 Address Inputs
IP & CIDR Netmask: 10.0.0.1/8
IP & Netmask: 192.168.0.1 255.255.255.240
IP & Wildcard mask: 172.16.2.1 0.0.1.255
Example IPv6 Address Inputs
IP & CIDR Netmask: 2607:fb90:30de:5017::/64
*Note: Wildcard mask is inverse of subnet mask.
