Question

For each of the following IP address, what does the router do if packets with the following addresses arrive? Justify your answer.

i. 128.1.49.7
ii. 128.1.64.1
iii. 128.1.52.240
iv. 128.1.60.120
v. 128.1.51.20

Answer 1

A router will forward packets based on its routing table which determines if the IP addresses are for local or external destinations. Specific actions depend on the network's configuration and routing protocols; without details on subnetting, only general behavior can be assumed. option 1 is the correct answer.

Step-by-step explanation:

When a router receives packets with specific IP addresses, it decides what to do based on its routing table and protocols. Here's what could happen for each provided IP address:

1. 128.1.49.7: The router will forward this packet to its destination based on the routing table if the address is within the network or the subnet, or it might send it towards the default gateway if it's an external address.
2. 128.1.64.1: Similar to the first, the router will either route it internally or externally depending on whether it's part of the network or not.
3. 128.1.52.240: This address would also be either routed directly if it belongs to the local network, or sent to another router or default gateway if it’s outside the local network.
4. 128.1.60.120: As with the others, it will be routed based on the routing table's prescribed path for this IP address.
5. 128.1.51.20: Again, the router will look at its routing table to decide if the packet should be sent through the local network or forwarded to a different network.

It's important to note that without specific details on the subnetting or the routing protocols at work, we can only assume the general behavior of the router.
