Some IP address ranges are only for use in private networks that cannot be accessed from the global internet. Typically these will be used by groups of machines "hidden" behind a firewall. Three ranges are defined by the agreed standard RFC1918. These are as follows:

  • 10.0.0.0 - 10.255.255.255
  • 172.16.0.0 - 172.31.255.255
  • 192.168.0.0 - 192.168.255.255

As these addresses will be used many times over throughout the world, there is no way to detect where in the world the user is located.
