Lab 3 1: ARP Observation - jude-lindale/Wiki GitHub Wiki

Tech Journal Summary In this lab we were tasked with running commands in Command Prompt and using wireshark. We started by starting a trace with wireshark, running the command "netsh interface ip delete arpcache" to delete any saved ARP results, and then ping the default gateway. Then we had to look through what was captured by wireshark but we only wanted to see the ARP results so everything else got filtered out. Then we were task with doing the same thing but this time we had to ping Google's Public DNS server.

Commands

• ipconfig/all: will show you all of the ip configurations
• netsh interface ip delete arpcache: this command will delete any saved ARP results
