::1 is the compressed format IPV6 loopback address 0:0:0:0:0:0:0:1. It is the equivalent of the IPV4 address

If you are trying to find your machines public IP address then you can use whatsmyip.org.

If you want to know the IP address of a network interface then you would need to tell us what operating system you are using.

  • ipconfig is the command to use to find the IP address of a network interface in Windows 7. If you are having problems with geolocation then it is most likely the public IP address that you want.
