Assuming classless addressing, and given the shown IP addresses allocated to hosts of each network, find the network addresses and prefix lengths (both written together in the dotted decimal notation ------------/--) of each of the four network segments above. (Hint: Remember that all hosts in a network must have the same netid. Also, keep the allowed number of hosts as minimum as possible in each network) 2. Using the routing tables of R1 and R2 below, determine the output interfaces crossed by a packet generated at Host 192.168.0.111 to the destination address 150.60.71.33.

Now assume that router R1, whose IP address is 150.60.70.1, also acts as a network address translation (NAT) device with the following table, find the destination of an incoming packet to the network with a destination address 150.60.70.24 and port number 7. Private Addresses Global Addresses 150.60.70.24; 6 150.60.70.1; 7 150.60.70.24; 7 4. If Host 192.168.0.5 wants to broadcast a packet on Network B, what IP address must this host use as a destination address for this packet? 192.168.0.5 192.168.0.29 192.168.0.16 R2 B 192.168.1.117 192.168.1.68 192.168.0.111 192.168.0.35 192.168.0.105 C 192.168.0.210 D R1 192.168.2.117 192.168.3.220 192.168.2.15 E W X Y Z To Internet The above figure shows 4 small networks connected to each other using two routers. 1.
