Lab 2‐2: Observing LAN Activity - TheWumpDump/NET-150 GitHub Wiki

Overview: I used ping commands and Wireshark to track basic LAN traffic.

Commands used (in cmd):

  1. ping [ip] - Pings the ip listed
  2. ipconfig /all - Shows all info about LAN connections

Questions:

  • A MAC address, or Media Access Control address, identifies a single device within its LAN. it consists of an OUI (the first 8 digits) and the actual device identifier. the OUI identifies the manufacturer of the device.
  • To get a MAC address on windows, simply go into command prompt and type "ipconfig /all", then look for the MAC. for other devices, it may appear in a settings menu or require a different command.
  • Wireshark is a packet tracker; it identifies single packets of data and where they came from or are going.
  • Protocols in Wireshark are listed in a column in the data stream if that's what you mean.
