Show Suggested Answer

From what I recall, using "-n" prevents tcpdump from resolving IP addresses to hostnames, which makes sense for faster output.

I’m a bit confused; I thought "-n" meant to enable name resolution. I need to double-check my notes.

I remember practicing a question about tcpdump where we had to choose between enabling or disabling name resolution. I think "-n" was for disabling it.
