Use the saved output to indicate the number of matches for each of the preceding IP addresses. Explain how PC1 resolves multiple matches in the routing table. Include only relevant output data in your report to support your analysis of the data.

The IP address in question is compared to each entry in the list in ascending order, and by
performing a bit-wise AND with the corresponding netmask. A host-specific routing entry is
always placed at the top, and a default routing entry is always placed at the bottom. The netmask
of a host-specific entry is set to 255.255.255.255, and thus will give an exact match. Any network
entry will have a netmask defined to match the network-prefix of the IP address. The default entry
will have an IP address of 0.0.0.0 and netmask of 0.0.0.0. Since all bits are set to zero, any address
1) When PC1 pings 10.0.3.9, PC1 first searches its routing table about the information how to reach 10.0.3.9. A match is found at the first line (gateway 10.0.1.81) and no further checking is
needed. Then PC1 tries to obtain the MAC address of 10.0.1.81 by sending ARP request. However, gateway 10.0.1.81 does not exist and no ARP reply is received. The ping command times-out after two successive ARP requests are sent. PC1 decides the destination 10.0.3.9 is not reachable.
2) For pinging to 10.0.3.14, the first match is the entry for network 10.0.3.0. The matching process is stopped here and again, gateway 10.0.1.61 does not exist and no ARP reply is received. Alsothe destination 10.0.3.14 is not reachable.
3) For pinging to 10.0.4.1, there is no explicit match, thus the default entry is used. Since gateway 10.0.1.71 also does not exist, no ARP reply is received. Not reachable.
