The IP location may vary from tool to tool due to the different update times of IP detection databases. We are using a paid IP detection tool called Maxmind, a well-known IP database provider. That result can be trusted well.
Besides, we recommend you use the IP you get to test your use case. If your use case uses a different IP database from ours and affects your business, please contact Support, rest assured we will try our best to find you a proper IP.
