1. Introduction The objective of this report is to analyze each of the 1,509 packets in a given trace file using Wireshark to understand the interaction between the hosts, routers, and servers in a network. The main host is at University of California Santa Barbara with Media Access Control (MAC) address Dell_f0:8e:55 and Internet Protocol (IP) address 128.111.52.185. The host’s device is a computer running on Microsoft OS. The host will transfer and receive packet of data from certain websites, for example Google, through Transmission Control Protocol (TCP), search for other hosts/devices’ IP address in the network through Address Resolution Protocol (ARP) using the router or other hosts/devices search for the host, ping certain IP addresses, or trace a route to certain addresses. Figure 1 is a list of MAC and IP addresses that are found in the trace file. Figure 2 shows the complete list of the protocols used in the trace file with their respective acronym, name, and layer that can be referenced to if needed.
