Question

The address of a class B host is to be split into subnet with a 6-bit subnet number. What is the maximum number of subnet and the maximum number of hosts in each subnet?

• A. 64 subnets and 1024 hosts
• B. 62 subnets and 1022 hosts
• C. 62 subnets and 262142 hosts
• D. 64 subnets and 262142 hosts

Answer 1

The correct option is B 62 subnets and 1022 hosts

The class B is defined as follows

Maximum number of subnets
$=2^6-2=64-2=62$
Maximum number of hosts is in each subnet
$=2^{16-6}-2=2^{10}-2=1022$
