ISP Detection: My Network Provider Houdini

Hey everyone,

I'm trying to get a handle on my user base's actual internet service providers for better analytics and fraud detection. You know, the usual SaaS founder grind.

• The Current Headache: My existing ISP detection methods are playing hide-and-seek with the actual network provider data. It's like my software thinks every user is browsing from a data center in Virginia, even when they're clearly on their home Wi-Fi in Topeka.
• What I've Thrown at It:
  • MaxMind GeoIP2 (both the paid Enterprise and the free GeoLite2 DBs).
  • A bunch of online "What's My IP" tools – just to cross-reference.
  • Even cobbled together a Python script using a few public IP APIs, hoping for a magic bullet.
• The Hilarious (and Frustrating) Results:
  • MaxMind is great for country/city, but for the actual network provider? Often just spits out "Amazon Technologies Inc." or "Google LLC" – even for residential IPs. It's like my users are all secretly cloud engineers.
  • Many IPs come back as "unknown" or "corporate" when I know for a fact they're standard residential connections or mobile data.
  • This lack of accurate network provider info is making it tough to segment users properly and spot suspicious activity. Are they real users or bots hiding behind a cloud network provider? Who knows!
• The Plea for Sanity: Has anyone cracked the code on truly accurate ISP detection? Are there any services (paid or otherwise) that actually deliver reliable end-user network provider identification? I'm open to anything that stops my network provider data from acting like a digital Houdini.
