IP lookup data discrepancies?

Hey everyone, quick follow-up to my earlier post about growing organic traffic for my geolocation tool.

I'm now running into a technical snag with IP lookup accuracy. We're using multiple providers to cross-reference location data, but often get conflicting results, especially for city/region.

This is causing issues for users and impacting data reliability. Here's a simplified example of what I mean:

{
    "ip": "8.8.8.8",
    "provider_A": { "city": "Mountain View", "region": "CA", "country": "US" },
    "provider_B": { "city": "Sunnyvale", "region": "CA", "country": "US" }
}

What are your best practices for handling such IP lookup data discrepancies? Do you have a preferred method to reconcile or prioritize data from different APIs, or perhaps a single, highly reliable service you'd recommend?

Thanks in advance!
