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 IP/Mask or IP/CIDR:
Example IP 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
*Note: Wildcard mask is inverse of subnet mask.
Here is the subnet calculator results for 184.108.40.206/24.
