3. Is the host 128.235.205.16 on the network 128.235.204.0/24? 4. We wish to create 16 subnets in a /20 network. Assume that we wish to use minimum number of bits for the subnet id. a. How many bits will be used for the subnet id? b. How many possible hosts are there on each subnet? c. What is the mask for the subnets in slash notation? 5. An organization has a network address of 135.102.192.0/18. The organization wants to create subnets so that each subnet can support 500 hosts. a. How many bits of host id are required? b. How many bits of subnet id are there? c. How many possible subnets can this organization have? An ISP has CIDR block 135.102.192.0/24. The ISP wants to create 4 sub-blocks of equal size from this block. 6. How many bits should the ISP add to the mask for the subblocks? What are the network addresses (in dotted decimal with the mask in slash notation) for each subblock? What is the maximum number of hosts in each subblock? a. b. c
