Exactly! I also ran into this issue and had to do the same, I should append that to the end. Not sure why that happens. I actually usually script my root profile and user profile bashrc to mirror so that when I make alias changes to one, they work across both users so I didn’t even think about mentioning it for anyone else.
I like dnsdumpster.com because it provides an easy to read layout of any domains DNS records along with a map of the connections. Regarding being more creative, you’ll have to do some more research unfortunately. I don’t want to make it too easy for the bad guys to have more tricks under their tool belt if they stumble across this 😇
