An organization is given the following public IP address: 140.192.50.2. The organization uses the following private IP address block: 192.168.0.0/16. The organization has the following two departments: technical (tech), management (man). Assume that the organization IP address block is divided into these two departments equally. tech1 gets the first available IP address in the IP address block assigned for the technical department. Similarly, man1 and man2 gets the first two available IP addresses in the IP address block assigned for the management department. If you need any other IP address, you could use from available addresses in the management IP address block. For each host and router interface, the figure shows the corresponding MAC addresses. S represents the switch, R represents the NAT-enabled router. Assume that the routers and hosts are correctly configured with the correct routing information, i.e., their forwarding tables are correctly configured. Assume further that the switch tables of the switches and the ARP tables of the router and all hosts are initially empty. Assume that the host tech1 is sending an HTTP request to a Google web server. The host tech1 knows the Google web server's IP address (223.1.3.2). For all the packets that will be transmitted over link L1 and L2 (in both directions), provide the information requested in the table below. Note that some of the requested information in a row may not be applicable (N/A) for some packets. Packets should be listed in the order of their appearance on the links. Please ignore the HTTP reply packet. Please explain your solution (how you assign IP addresses and construct the table). It is necessary for getting points.
