   6. F172.64.0.0/16
7. 7You are working in a data center environment and are assigned the address range 10.188.31.0/23. You are asked to develop an IP addressing plan to allow the maximum number of subnets with as many as 30 hosts each.Which IP address range meets these requirements?

   1. A10.188.31.0/27
   2. B10.188.31.0/26
   3. C10.188.31.0/29
