[BlueOnyx:20548] GeoIP lookup errors

[Colin Jack]

We are using Michael's AV-Spam on our mail servers and are seeing some funny results from GeoIP:

Jan 18 10:49:27 pegasus milter-geoip: Connect from IP: 46.101.101.181 - Country code: RU
Jan 18 10:49:27 pegasus milter-geoip: BLACKLIST: Connection (46.101.101.181) is from blacklisted country RU

Now that has rejected as a Russian address but 

http://whois.domaintools.com/46.101.101.181

It is based in Frankfurt.

Where does GeoIP get its matching lookup from?
We block Russia but not Germany and our users are complaining. :)
