Welcome to the Subnetting Trainer!

This is a standalone subnetting practice tool to help you pass your CCNA — Drill the magic-number method until it's second nature!

Below you are given the IP address with the subnet mask / CIDR.

Can you figure out the Network Address, Broadcast Address, First Usable Host, Last Usable Host, and the total Usable Host Count?

Happy Subnetting!
