Two devices that share data with each other are often referred to as endpoints with reference to Wireshark. As we have noticed and observed, if a host intends to talk to another host on the network, they would require some form of address to send and receive packets—yes, I am talking about the physical address that every device holds.

Every host is able to communicate with the help of an Network Interface Card (NIC) that holds a physical address (often termed as a MAC address), and the same address is used for communication over a local network. Devices that communicate in this kind of infrastructure are termed as endpoints. Wireshark gives us the facility of analyzing and collecting information regarding these two devices.

Let's say, for example, that we are observing heavy network traffic flowing across a network, which is kind of unusual according to our daily traffic pattern. Now, we want to figure out due to which device(s) the traffic pattern differs. For us, the Endpoints...
