Q6. (10 marks) Consider a datagram network using 8-bit host addresses. Suppose a router uses longest prefix matching and has the following forwarding table: Prefix Match Interface 1 0 10 1 111 2 otherwise 3 For each of the four interfaces, give the associated range of destination host addresses and the number of addresses in the range Q2. (10 marks) Consider the following topology. a. Suppose A would like to send an IP datagram to C and assume that A's ARP cache does not contain C's MAC address. Will A perform an ARP query to find C's MAC address? Why? b. In the Ethernet frame containing the IP datagram destined to C sent from A, what are the source and destination IP and MAC addresses?
