1. the big picture: internet infrastructure
2. the tiny picture: what's in a data packet?
- your router's IP address
- the website host's IP address
- website content
- a bunch of other stuff
- data packets make up the requests that your browser makes to a server
- you can look at your browser's network requests by going here (this is for firefox, but all browsers have some version of "developer tools" that let you look at these):
3. two useful terminal commands
traceroute tells you the IP addresses your packet hops to on the way to the server.
whois tells you information about the website host. you can do
whois [IP address] or
whois [host name] since host IP and host name are just different versions of the same information.
pro-tip: you can always type
man traceroute or
man whois to learn more about the command.
