1. If we know a printer's IP address is 200.23.16.202 and subnet mask is 255.255.255.224, then, what's the network ID and host ID of this printer? Write both in the standard dot-decimal format without attaching the subnet mask. 2. If there is also a computer whose IP address is 200.23.16.170 with the same subnet mask as the printer in the previous problem, are they both in the same network? Yes or no, explain your answer. Also, compare their host ID. 3. Suppose the network that hosts the above printer is re-configured with other networks in the building. After re-configuration, the printer's IP address would remain the same but its network is changed with a new subnet mask, which is changed to 255.255.255.128. This means, even the printer's IP address looks the same, its network ID and host ID are different from those before re-configuration. Find the new network ID and host ID of this printer. You must write both in the standard dot-decimal format without attaching the subnet mask. 4. (20 points) Given a laser color printer whose IP address is 192.135.250.180/24, the network administrator of the company wants you to divide the printer's network into 30 subnets to support 30 project teams such that each team has its own separate network. After re-configuration, the printer will be hosted by a smaller and different subnet. For this particular subnet, what is its possible IP range, from its network IP to broadcasting IP? *Note that these are two special and reserved IPs of the network, they are not a valid host IP and cannot be used by for any hosts of the network. (1) What is the new IP of the printer in CIDR form? (2) How many hosts can connect in each new subnet? 1.
