Explanation:

For 10 numbers of subnets:

  • For Class A network, the byte allocation is network.host.host.host.
  • First byte range for class A network is 1-126.
  • Example for class A network address is 10.52.36.11.
  • Using 1 bit, the user can create 2 subnets.
  • Using 2 bits, the user can create 22 subnets which results in creation of 4 subnets...
