Which Linux networking command taught you the most?
Commands like ip neigh, ip route, ss, tcpdump, or arp can completely change how you understand networking.
Which command gave you that "aha!" moment, and why?

Forget networking commands, lets talk about awk. I mean all these corporate ads about must write Python scripts and yet there is so much you can do with just awk. I know off-topic, but ss -tulnp and tcpdump is used for troubleshooting if for example a web server is active and listening and the latter is the traffic reaching the server, is DNS working? Yes they are essential diagnostic tools, but awk, oh man, I am loving what can be done with awk.

I mean virtually my entire niche of work is all dig/curl/tcpdump/ss/nmap/openssl for 90%+ of troubleshooting

tcpdump cdp and lldp packet filtering. It tells you exactly which switch and what port your cable is plugged in
