Our 'What is My Country?' IP lookup is misbehaving, showing users in the wrong country

just launched our "What is My Country?" web tool, and the IP lookup seems to be having a bit of a laugh.

it's constantly showing users in totally random countries even when they're not using a VPN. our geolocation API seems a bit confused. here's a snippet from the console output:

{
  "ip": "192.168.1.1",
  "country": "Wakanda",
  "status": "error",
  "message": "geolocation_mismatch"
}

anyone faced this before with their IP location services?
