tech calculator
Calculate CIDR, subnet masks, and address ranges.
Keep this network calculator handy for IP addressing, routing setup, or certification study.
Network address
192.168.1.0/24
Formula
Network = IP AND subnet mask; Broadcast = network OR inverted maskThe calculator converts the IPv4 address into a 32-bit integer, applies the CIDR mask, and derives the network, broadcast, and host range.
Step by step
Example
192.168.1.10/24 belongs to the 192.168.1.0/24 network with 254 usable host addresses.

Guide
Subnetting divides a larger network into smaller, logical subnetworks (subnets) to improve performance, security, and address efficiency. The CIDR prefix determines the subnet mask by setting the number of shared network bits.
This tool applies bitwise masking to an IPv4 address to find network bounds, usable hosts, and the broadcast address, helping administrators manage address blocks.
CIDR notation
Classless Inter-Domain Routing notation, which specifies network prefix length (e.g., /24) to define mask size.
Broadcast address
An IP address used to target all hosts on a subnet simultaneously.
The first address in a subnet is reserved for the network address itself, and the last address is reserved for the broadcast address. Usable host IPs sit between these boundaries.
A 32-bit number that hides or masks the host portion of an IP address, leaving only the network portion visible to routing protocols.
