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.

Options:

  • Auto‑fill non‑interesting octets pre-fills the octets that aren’t part of the subnet calculation. For example: with a /24, the first three octets are filled in each answer row.
  • Auto‑check automatically checks a row once all four octets are entered.
