Your computer's IP address / subnet mask is 128.65.34.121 / 255.255.255.192. You want to send an IP packet to 128.65.34.135. Is the destination on the same subnet as you? In other words, is the destination local or remote? Why? What IP address do you send the ARP request for? 4. Using the proper default subnet mask, is 12.16.1.0 a valid host IP address? 5. The IP address / subnet mask pair 65.32.6.4 / 255.255.255.0 is a (subnetted/natural) class address. 6. Subnetting a class C address: Scenario: Your company has been assigned a single Class C IP address of 193.16.8.0.
