🌐 IP Subnet Calculator
Calculate network address, broadcast address, host range, and total hosts from an IP address and CIDR prefix.
What is Subnetting?
Subnetting divides a larger network into smaller, more manageable sub-networks. Each subnet has its own network address, broadcast address, and range of usable host addresses.
Understanding CIDR Notation
CIDR (Classless Inter-Domain Routing) notation like /24 specifies how many bits of the IP address are used for the network portion. A /24 means 24 network bits and 8 host bits, giving 256 total addresses (254 usable hosts).
