Trouble with IP address lookup
0
Hello everyone! I'm super new to this whole SaaS/web tools thing and just launched a very simple tool called 'What is My ISP?'. It's meant to help users quickly find their internet service provider based on their IP address.
I'm running into some frustrating accuracy issues, especially with getting reliable ISP data. I'm hoping some experienced folks here can point me in the right direction.
- The Core Problem: My tool relies on IP address lookup services to identify the ISP. While it works okay for major providers, I'm finding a lot of inaccuracies or generic results for smaller, local ISPs, or when users are on mobile data.
- What I've Tried So Far:
- I started with some free IP geolocation databases (like MaxMind's GeoLite2).
- Then I experimented with a few public APIs (e.g., IP-API, Abstract API) for real-time lookups.
- Where I'm Struggling:
- Data Accuracy: Often, the reported ISP is a large backbone provider rather than the actual local provider the user pays for.
- Coverage: Specific regions or smaller ISPs seem to be poorly covered.
- Cost vs. Accuracy: The more accurate (and often real-time) services seem to jump quickly into paid tiers, which is tough for a beginner project with no revenue yet.
- VPN/Proxy Detection: Sometimes it reports a VPN provider as the ISP, which isn't what I'm looking for.
- My Main Question: What are the best (and ideally, most affordable for a bootstrapped project) IP address lookup services, databases, or strategies you'd recommend for reliably identifying a user's actual Internet Service Provider? Are there specific industry secrets or lesser-known providers that offer better accuracy without breaking the bank?
- Thanks in advance for any help or guidance!

The challenge with ISP data accuracy, especially for smaller providers or mobile, is common as free IP geolocation databases often prioritize backbone networks. For more reliable network intelligence and actual ISP identification, you'll need to leverage more specialized services:
- Premium IP Geolocation APIs: Services like IPinfo.io, IPStack, or even MaxMind's GeoIP2 Enterprise (beyond GeoLite2) offer significantly better accuracy for ISP, organization, and ASN data. They actively maintain and update their datasets, which is crucial for dynamic network information.
- VPN/Proxy Detection: Many premium IP lookup services include VPN or proxy detection as a feature. If not, consider integrating a dedicated VPN/proxy detection API alongside your primary IP geolocation API to filter out non-ISP traffic.
- Cost Management: For a bootstrapped project, explore the free tiers or trial periods of these premium services. Prioritize the most critical lookups or implement caching to reduce API calls once you scale.
