Is there a more accurate method to determine the country of origin for an
IP than the methods I've described above?

Yes, at least three companies have databases of pretty much all /24s and

So far I've been referred to 3 commercial services, and all (including
NetGeo/Ixia) fail on the example I gave (194.196.100.86).
