Find first sub network ID, Fist address, Last address and Braodcast for each of the following given addresses.a. 17.23.120.8b. 252.5.15.111After establishing a connection with the local DNS server PC1 now knows the IP and MAC addresses of PC2. Suppose PC1 [IP Address: 192.168.2.1, MAC Address: 0010.1191.A946] is sending an ARP packet to PC2 [IP Address: 192.168.2.2, MAC Address: 0110.1290.AD23]. What will be written in the target MAC address before the packet reaches PC2 ?Does a router direct packets to MAC addresses ? If your answer is YES explain how, If the answer is NO explain what device can do it and how.
