About IP Subnetting

Network Address: The first address in a subnet, identifies the network itself.
Broadcast Address: The last address, used to send to all hosts on the subnet.
CIDR Notation: Compact way to specify a subnet using /prefix (e.g., /24 = 256 addresses).
Wildcard Mask: Inverse of subnet mask, used in ACLs and routing protocols.

All calculations happen locally in your browser.
