Does it spoof IP location?

Does the test database contain sensitive data? If not, you can ignore the ransom.

What is the different compare to other sites such as ipaddress.my?

It looks like a IP geolocaion API. However, it has missing authentication under the readme.

How do you detect VPN or proxies? Are you using 3rd party services such as IP2Location or Maxmind?

I don't like the latency of web API. Therefore, I'm using the free IP2Location LITE for fast local lookup.

Do you have any issue with the ESP for high bounced rate? If yes, then cleansing is a good way to recover from it.

Otherwise, your list is just fine and you do not need to have email validation.

How about software SaaS which is charging monthly?

What does it do differently than IP2Location, IP2Proxy and Maxmind?

It takes longer time through ICANN. Ceast and desist is the cheaper and faster way.

The IP address is like a temporary phone number. It could not pinpoint the person persistently but can be tracked down with the help of ISP.

Other information you can retrieve from IP address is geolocation information such as https://www.ip2location.com

I agree that IP geolocation is a good approximation. It is never accurate up to street level.

Meanwhile, there is API to detect VPN, so that we can aware that the geolocation is good up to the server physical location.
