SUBNET BLITZ

race the clock · do the bit math · keep the streak alive

How to play

A random CIDR block appears (e.g. 10.14.200.0/26).
Answer one question about it: usable hosts, subnet mask, network address, broadcast address, or how many smaller subnets fit inside.
Tap an option (or press keys 1–4). Beat the shrinking timer.
Correct answers bank leftover time as bonus points and grow your streak multiplier.
Wrong answer or timeout costs a life. You have 3. Push for a high score.

Best score: 0
