IPv4 BIT COUNTING — Subnetting Made EASY!

If 192.168.1.1 → Binary still confuses you, this is the post you needed 👇

Every octet follows the same rule:
128 | 64 | 32 | 16 | 8 | 4 | 2 | 1
Turn ON (1) the bits ➝ add them ➝ get the decimal value

🔹 Why this matters:
• Subnetting without calculators
• Faster CCNA exams
• Confident IP addressing in real networks

Pro tip:
Once you master bit weights, subnet masks and CIDR become automatic.
