Consider a datagram network using 8-bit host addresses. Suppose a router use longest prefix matching and has the following forwarding table
For each of the four interfaces, give the associated range of destination host addresses and the number of addresses in the range.

number of addresses in the range of interface 0 = 2^6 =64
number of addresses in the range of interface 1 = 2^5 =32
number of addresses in the range of interface 2 = 2^5 +2^6 =32+64 =96
number of addresses in the range of interface 3 = 2^6 =64
