I thought of that, but tried a few (incomplete) tests here in the LAN with
the IPv4 version and it returned the correct number of hops. I say
incomplete, because I didn't try to cross the AS border. Over the Internet,
it returns high numbers that look close to what I'd expect (64-hops) to be,
indeed.

Yes, it does. I just don't know if it IS a correct measurement, or just
looks like it.
