Help! My 'What is My ISP?' tool's internet service provider identification is totally off lately
hey AdsVolt community! so, we run this neat little web tool called 'What is My ISP?' and usually, it's super handy for users who just wanna quickly figure out their internet service provider. it's supposed to be straightforward, you know? hit the page, boom, there's your ISP info.
but lately, our internet service provider identification results have been acting... well, kinda bonkers. instead of showing an actual network provider like 'Comcast' or 'AT&T' for a regular home user, it's often spitting out generic stuff like 'Cloudflare' or 'Google Public DNS'. it's a bit embarrassing when our own tool gives info that's clearly not their primary internet service provider. like, come on, software, get it together!
- why might this be happening more frequently now?
- is it something on our end we should be looking into, or are more users just routing thru VPNs, specific DNS services, or even corporate networks that obscure their true network provider?
- any tips on how to improve the accuracy for internet service provider identification, maybe some different lookup methods we should explore?

Regarding your 'What is My ISP?' tool's accuracy, what you're observing isn't necessarily your software "acting bonkers," but rather a reflection of how internet traffic is increasingly routed. When your tool identifies 'Cloudflare' or 'Google Public DNS,' it's accurately reporting the entity that owns the egress IP address your server sees. This happens frequently when users are routing their traffic through a VPN, a corporate network proxy, a public DNS resolver service (like Google's 8.8.8.8, which can also act as a resolver and sometimes a proxy), or even a Content Delivery Network (CDN) that might be intercepting or routing traffic. This trend is accelerating due to increased privacy awareness, widespread adoption of VPNs, remote work setups, and services like Cloudflare WARP that intentionally obscure the direct connection to the end-user's last-mile internet service provider. Essentially, your tool is seeing the proxy or the network edge, not the residential ISP.
To improve the accuracy of internet service provider identification, or at least how you present the information, consider the following. Your current method likely involves reverse DNS lookups and WHOIS queries on the detected IP address, which is the standard approach for identifying the owner of that specific IP. To get closer to the *actual* residential ISP, you would need to leverage more advanced IP geolocation databases that provide Autonomous System Number (ASN) details. Services like MaxMind GeoIP2, IPinfo.io, or even custom lookups against RIPE, ARIN, APNIC databases can provide the ASN, which often points directly to the last-mile ISP or a major peering network. However, it's crucial to understand that if a user's traffic is genuinely proxied through a VPN or corporate network, you will *never* be able to reliably identify their true home ISP. The best approach is often to clearly label your tool's output as "Detected Network Provider" or "Egress IP Owner" rather than simply "ISP," managing user expectations and accurately reflecting the technical reality of the detected network identification.

Answered 1 day agoAh, got it! This totally explains it tho. I'm saving this thread to send to a couple of friends who run similar tools and are probably scratching their heads too.
