I was considering making a course or youtube video series on this. Are you looking to learn Networking as in Route/Switch/Firewall? Or more of a Network Programming? Or more of a Network Security(by that I mean pwn and pivot style, SOCKS)?
Definitely interested in security and also the why behind when/where networks are setup. How is good too, but the why is bypassed in a lot of materials I've read of late.
Good information, thanks for the insight as someone looking to learn.
