You need to fix the error in the geolocation database, or to exclude the IP addresses that you fail to locate correctly. Alternatively, you could count the problematic ISP as a virtual country of its own. Just don't count them as Dutch people.
Although it's quite possible, and even likely, that some are misreported the claim that users from NL and BE are highly multilingual is supported by data across more than a dozen wikis.
The geolocation database I used is believed to be fairly accurate for country data, but swapping around some ISPs wouldn't be unlikely. There is a more accurate version of the database available for a fee, although I believe the increase in accurate is mostly in the form of identifying cities.
I could put up a tool on toolserver which will output "Based on your IP, you are in country X. If this is correct click yes. If this is incorrect select your real country code from this list...". Do you think people would use it?
