How many entries would be in H4's ARP table due to these messages? For the next three parts assume all caches are cleared before machine H4 sends a single ICMP ECHO request to machine H3 How many packets are transmitted on the network segment NET 1 (including the ECHO request and reply)? How many packets are transmitted on the network segment NET 3 (including the ECHO request and reply)? How many packets are transmitted on the network segment NET 2 (including the ECHO request and reply)? 2.
