Question 2: Part of a networking infrastructure consists of three routers R1, R2, and R3 and six networks N1 through N6, as shown in Figure 1 below. All address entries of each router are also given as seen in the figure. A packet with the destination IP address 195.25.17.3 arrives at router R1. (b) Explain what router R1 will do in order to forward the arriving packet. Then, find the exact network ID field of each network in binary form (you can use online converters). Finally, find the destination network for the packet (show your work).

(c) Explain where user End systems (hosts) can be connected in this network and why? Then, specify how many hosts can be addressed in network N1 and N4.
