A note about the IP addresses: Some ad networks/analytics software does not store your IP address, but an anonymized version of it (eg. drop the last octet[1] or an store only an hash). I believe that they must do this in order to operate legally in certain countries.

They can still store the geoIP information without storing the IP, though.
