I have some questions on Week 5 short lecture on Internet Primer, in particular on the host and ip address table that was being showed at 11.37 of the video. The questions are as follow:
In the the attached pictures: 1. What does io-in-f138.1e100.net really refers to in the 1st picture?
From David's lecture, I understood that ip address will map to a particular domain name. But why in this case it is being mapped to io-in-f138.1e100.net instead of google.com (as in picture 1)? I did tried to search for io-in-f138.1e100.net in the address bar, but it returned a 404 Not found error.
How does io-in-f138.1e100.net being translate to google.com as in picture 2?
