Online IPv4 Subnet Calculator
This IP Subnet Calculator covers both Classless Inter-Domain Routing (CIDR) and traditional class-based subnetting. It helps network engineers and students calculate the network address, broadcast address, and usable IP range for any given IP address and subnet mask.
Understanding Key Terms
- Network Address: The first address in the subnet, used to identify the network itself.
- Broadcast Address: The last address in the subnet, used to send data to all hosts.
- CIDR (/xx): A compact way to represent the subnet mask (e.g., /24 is 255.255.255.0).
