How IP Subnetting Works
This calculator takes an IP address and a subnet mask to determine key information about the network segment. By performing a bitwise AND operation between the IP and the mask, it finds the network address, broadcast address, and the range of usable IP addresses for hosts on that subnet.
Frequently Asked Questions
What is a subnet mask?
A subnet mask is a 32-bit number that separates an IP address into its network and host portions. It defines which part of the IP address refers to the network and which part refers to the individual host.
What are the Network and Broadcast addresses?
The Network Address is the first address in a subnet and is used to identify the subnet itself. The Broadcast Address is the last address and is used to send messages to all hosts on the subnet. Neither can be assigned to an individual device.
