|Subnets calculation



Q: Break the 200.1.1.0/24 network into 10 subnets.

  1. networks = 10

  2. bits to borrow = 4 (2^3 = 8 | $2^4$ = 16 → so we go with 2^4)

  3. increment number = 16 - 2 ( - 2 because it cannot be 0 or 1)

  4. new subnet mask = 14 - 254 = 240 = 255.255.255.240 OR /28

  5. convert the IP into Binary =
paint

- here we’ve found 3 subnets and you can find other combination to reach 10 subnets.
