The address of a class B host is to be split into subnets with a 6-bit subnet number. What is the maximum number of subnets and maximum number of hosts in each subnet?
  1. A62 subnets and 1022 hosts
  2. B64 subnets and 1024 hosts
  3. C62 subnets and 254 hosts
  4. D64 subnets and 256 hosts
Show answerHide answer

Correct answer: (A) 62 subnets and 1022 hosts

Explanation

Class B has 16 host bits. Using 6 bits for the subnet leaves 10 host bits. Number of subnets = 2⁶ − 2 = 62; hosts per subnet = 2¹⁰ − 2 = 1022.
