IP Guide is also using MaxMind, I'm not familiar with many other data sources for that kind of data. Are you seeing discrepancies?

No rate limits or auth for requests, but as mentioned below the api starts to load shed at 2k concurrent requests.

Thanks. Yeah, I was just hoping it might have access to some different data. I've seen no discrepancy. I tried one IP address that I've been trying to map, and I got the same answer.

Their city level data tends to be proprietary so maybe double check you’re ok in your use.
