The code currently does Unix.string_of_inet_addr by default, making the tool considerably less pure.

It would be nice if that was an opt-in hazard, or if, at least, there was a -n option to disable this behavior.

I know, I know, it's mostly a concern for the unfortunate souls among us that happen to use GNU software :-)

Example of why DNS resolution is problematic:

Alternatively, perhaps a pure DNS lib?
