Subnet Calculator
Calculate network details such as host range, broadcast address, and netmask from valid IPv4/CIDR.
Understanding Subnetting
Subnetting allows you to divide a network into smaller, more efficient subnetworks. This helps in reducing network traffic, improving security, and making IP management easier.
Glossary
- CIDR (Classless Inter-Domain Routing): A notation using a slash followed by the number of bits in the network mask (e.g.,
/24). - Valid Range: The span of IP addresses that can be assigned to devices within a specific subnet.
- Broadcast Address: The last address in a subnet, used to communicate with all devices on that network.
- Netmask: A 32-bit number distinguishing the network address from the host address.
