Binary and Hex: Speed Drills for Subnetting
How it works
Pick a drill and a level. Each round is 10 questions; the clock runs only while a question is open, and every answer shows the working (place values, nibbles, mask bits) so you learn the method, not just the number. Decimal to binary uses tap-to-flip bits. The place-value helper (128 64 32 16 8 4 2 1) is on to start; switch it off when you are ready.
There are 10 kinds of people: those who read binary and those who scroll past this joke. By the end of this page, you’re the first kind. — Nova
