  • Does Nanjee's IP geolocation-system work for IPv6 addresses?
  • Nanjee's IP geolocation-system is able to work for IPv6 addresses by design. However, at this point we do not apply it for IPv6 addresses as the IPv6 protocol is not widely used yet.


  • Do you foresee any privacy issue over data that you produce and deliver?
  • We neither have knowledge of any personal data of any IP host nor do we distribute them. We make estimations on geographical location of an IP address that may be hosted by individual device (e.g. PC, notebook, tablet, smart phone, etc.) or a non-individual device (e.g. a server) and we do not have ways nor do we distinguish these 2 cases.

    We also make estimation on geographical location of an IP address with 2 confidence levels, i.e., 35 and 70 (on a 0-100 confidence scale) that a particular IP host is located in a certain geographic area that can vary from several hundred meters up to several miles.
