Updated version of the classic Subnetting Practice question generator by Practical Networking.

Feedback? Mention it on my Discord server: pracnet.net/discord.

Instructions:

Each time you click "Next Problem" (or reload the page) a random IP address and CIDR value is generated.

You are then tasked to solve the Network ID, Broadcast IP, First Host IP, Last Host IP, and Next Network addresses for the target IP.

  • Auto‑check automatically checks a row once all four octets are entered.
