(16 points) Using CIDR (Classless InterDomain Routing) addressing construct the binary subnet part and host part of the following subnet mask: 10.8.12.5/22 (17 points) Given the following diagram represents a network with NAT (network address translation) protocol. It has a host with IP address: 10.0.0.3 and port number 2259 sending a datagram to the destination with IP address 117.120.30.177 and port number 80. Given that the NAT router IP address is: 125.44.22.9, apply NAT protocol to generate the (IP address, port number) of source and destination for links labeled with 2, 3, and 4.
