The '-n' filter in the tcpdump command is used to disable the name resolution of the host. This means that instead of displaying hostnames, the command will show IP addresses, which can be useful for troubleshooting network issues without the delay of DNS lookups.

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.

I think the "-n" option in tcpdump is used to disable name resolution, but I’m not completely sure.
