Exercise: Running traceroute
Heads up! You can now install the Terminal on your Windows machine so you can run the same commands as Mac or Linux users: https://www.microsoft.com/en-us/p/windows-terminal/9n0dx20hk701
Open up the Terminal (Mac/Linux), or Command Prompt if you don't have Terminal installed (Windows) and run
traceroute on any website you want. Keep in mind that on Windows Command Prompt you will have to run tracert instead of traceroute
For Mac/Linux users you can open the Terminal this way: Instructions
For Windows users you can open the Command Prompt this way: Instructions
For Windows users, to interpret tracert, check out this: https://www.inmotionhosting.com/support/website/how-to/read-traceroute.
If you see the IP addresses a little bit different than in my videos or the links above: The IP addresses you see may be IPv6. In this case, you will have to run:
tracert -4 google.com which forces IPv4 hops
If you see ***** (asterisk) in your output: If a packet is not acknowledged within the expected timeout (5seconds), an asterisk is displayed. Sometimes this can be due to your internet connection or
traceroute may show **** because of widespread use of firewalls and other security practices by the company that owns that server.
