This IP subnet calculator covers both IPv4 and IPv6 protocols, providing information such as IP address, network address, subnet mask, IP range, and more.
IP Calculator. ipcalc takes an IP address and netmask and calculates the resulting broadcast, network, Cisco wildcard mask, and host range. By giving a second netmask, you can design subnets and supernets.
The subnet calculator lets you enter a subnet range (CIDR) and see IP address information about that range You can type your range directly in CIDR notation, or use the optional Mask pull-down: 74.125.227.0/29.
Use this online subnet calculator to quickly calculate the network details for an IP address or CIDR range. We also have a REST API for use in your projects!
What information can I get from an IP address and a netmask? By entering an IP address and its corresponding netmask above, our tool will tell you what type of IP address it is, its broadcast address, the range of addresses it encompasses, its class, and more.
Results of the subnet calculation provide the hexadecimal IP address, the wildcard mask, for use with ACL (Access Control Lists), subnet ID, broadcast address, the subnet address range for the resulting subnet network and a subnet bitmap. For classless supernetting, please use the CIDR Calculator.
This IP subnet calculator displays comprehensive information about IPv4 networks (e.g., the number of usable hosts, IP ranges, etc.) and IP addresses (e.g., private or public, class, etc.). It's useful for designing networks, troubleshooting, and helping you pass your CompTIA Network+ exam.
