You could look at a pcap and look up documentation and make sense of it. And if you start up a packet capture on a home computer and do some browsing, If you knew programming you'd focus in on the parts that made sense first, like the http traffic....

No you learn L1 then L2, then L3.....Looking at PCAPs and looking up documentation for every value will lead you down an endless rabbit hole and is terrible advice to give anyone learning. You need structure. 

 

Starting out at http is also terrible. So he should know what http is but not ask how it gets to his router out to the internet? Or why does his PC have a gateway, what does it do exactly?

you aren't going to be getting a lot of BGP traffic.

Well at home, none.

 

There is a reason the TCP/IP model stops at layer 4 before just categorizing 5-7. If you dont understand routing and switching and just know Https, you dont know networking

I disagree. Looking at real network traffic and going down the endless rabbit hole of what each piece is doing is exactly how someone should learn. Starting from parts you already understand gives you structure. I never said you should stop with just knowing one layer. Regardless, OP got different recommendations from different perspectives; I don't see any value in going in circles with you.

Obviously my point. And the TCP/IP model doesn't 'stop at layer 4 before just categorizing 5-7', it combines layers 1 and 2, and 5-7, because the IETF felt the granularity was excessive for interoperability standards.

Schools, classes, certs, all have structure because it's how you learn. It's meant to guide you, teach you a foundation no matter what level you are at. Without it it just leads to confusion, going down a trail leading to nowhere.

Your method is probably the worst advice you can give to someone trying to learn.

Re-lookup the TCP/IP model and get back to me.

If you think schools and certs are the best way to learn............ LOL

 Yeah, no-- You are wrong. Layer 4 of the TCP/IP model consolidates layers 5-7 of the OSI model. Layer 1 of the TCP/IP consolidates layers 1-2 of the OSI model.
