1. From the point of view of router R4, what is the next-hop address for a packet addressed to host 161.22.0.15/18?

2. From the point of view of router R1, which of its interfaces would it choose for a packet being sent to network 161.22.0.0/18?

3. A host with an IP address of 200.11.60.36/24 has just sent a packet to a host with address 150.32.0.240/18. How many hops is required between source and destination?

4. A packet originating from network 220.10.40.0/24 arrives at router R1, however, R1 determines that the destination network is not in its routing table. What does R1 do with the packet?

5. A packet arrives at router R2 with a destination address of 140.21.0.10/22. Which interface port does R2 forward the packet out of?

6. A packet at router R3 has a destination address of 220.10.40.5/24. What next-hop address would R3 use for this packet?

7. A packet is waiting at router R4 for forwarding. If the next-hop was a "direct delivery", which of these three networks is the destination network? 150.3.0.0/16, or 150.32.0.0/18, or 220.10.40.0/24?

8. Complete the information in the routing table for router R2 as shown in the Answer Template for networks 150.3.0.0/16, 150.32.0.0/18, and the Default network. Show the masks in longest mask order using CIDR format.
