Total Addresses in Subnet:

To solve any subnetting problem, keep these fundamental formulas in mind: 2h2 to the h-th power is the number of host bits. Usable Host Addresses: (subtracting the Network ID and the Broadcast Address). Number of Created Subnets: 2n2 to the n-th power is the number of bits borrowed from the host portion. Magic Number:

  • Exercise: For 10.0.0.0/19, what is the block size in the second octet?
  • Solution: /19 is 255.255.224.0 (3 bits borrowed in third octet? Wait—check: /8 is default for A, /19 means 11 bits borrowed. Focus on the interesting octet (3rd). 256-224=32. Block size is 32 in the third octet).
