in my case im using ethernet->usbc adapter en1 will return nothing. I wonder if possible to iterate over enX for first match or maybe better provide hint as flag like --enX 8

sumel@mini-1 ~ % ipconfig getifaddr en4
sumel@mini-1 ~ % ipconfig getifaddr en5
sumel@mini-1 ~ % ipconfig getifaddr en6
sumel@mini-1 ~ % ipconfig getifaddr en7
sumel@mini-1 ~ % ipconfig getifaddr en8

Interesting I will think about adding a flag. The config is due for a refactor to simplify it further. However, at that point it is trivial to also edit the config manually since you only need the ip of rank 0.
