3. Consider a datagram network using 8-bit IP addresses. Suppose a router uses longest prefix matching and has the follwing forwarding table: (15 points) Prefix Match Interface 0 010 011 10 2 2 3 For each of the four interfaces, give the associated range of destination host addresses and the number of addresses in the range. Solution Consider a subnet with prefix 128.119.40.128/26. Give an example of one IP address (of form xxx.xxx.xxx.xxx) that can be assigned to this network. Suppose an ISP owns the block of addresses of the form 128.119.40.64/26. Suppose it wants to create four subnets from this block, with each blcok having the same number of IP addresses. What are the prefixes (of form a.b.c.d/x) for the four subnets? (15 points) 4
