IT Calculators
IP Subnet Calculator
Calculate subnet details from IP and CIDR.
What is the IP Subnet Calculator & How does it work?
An IP Subnet Calculator is a tool that helps determine the network address, broadcast address, and host range based on an IP address and its associated CIDR notation. This is essential for network administrators to manage and organize their networks efficiently.CIDR notation represents an IP address and its subnet mask in a compact form, making it easier to understand the size of the network. By inputting the IP address and CIDR into the calculator, users can quickly obtain detailed information about the subnet, including the range of usable host addresses.
Network Address = IP Address AND Subnet Mask
AND = bitwise AND operation
Parameters
Subnet Mask
—
Network Address
—
Broadcast Address
—
Host Range

Frequently Asked Questions
What is CIDR notation?
CIDR stands for Classless Inter-Domain Routing. It represents an IP address along with its subnet mask in a compact form.
How do I use the IP Subnet Calculator?
Enter your IP address and the corresponding CIDR notation into the calculator to get the network address, broadcast address, and host range.
What is a network address in an IP subnet?
The network address is the first IP address in a subnet used to identify the network portion of the addresses within that subnet.
What is a broadcast address in an IP subnet?
The broadcast address is the last IP address in a subnet used to send data packets to all devices on the same network.
How many hosts can I have in a subnet with a /24 CIDR?
A /24 CIDR allows for 254 usable host addresses within the subnet.
Can this calculator handle both IPv4 and IPv6 addresses?
Yes, our IP Subnet Calculator supports both IPv4 and IPv6 address calculations.
What is the purpose of an IP subnet?
An IP subnet divides a network into smaller subnetworks to improve management, security, and efficiency in network administration.
