My 'What is My ISP?' tool is misidentifying internet provider data

Hey everyone,

I'm banging my head against the wall a bit with my web tool, "What is My ISP? - Find Your Internet Service Provider." It's designed to be super straightforward: users visit, and it tells them their internet provider based on their IP address. Simple, right? Well, lately, it's been having some serious mood swings.

Instead of reliably showing, say, "Comcast" or "AT&T," it's decided to get a bit mysterious. Sometimes I get "unknown," sometimes it's a random data center name, and other times it's just plain irrelevant. This inconsistent ISP identification is making the tool look less reliable, which is definitely not ideal for a service built around accuracy.

Here's a snippet of what I'm seeing in my logs/console output:

// Example 1: User from residential IP
IP: 203.0.113.45
Identified ISP: Google LLC (Expected: Local ISP like 'Verizon Fios')

// Example 2: User behind a VPN/Proxy or just... confused data
IP: 198.51.100.12
Identified ISP: AS394354 - Cloudflare, Inc. (Expected: 'Spectrum' or 'T-Mobile')

// Example 3: Just gives up
IP: 192.0.2.78
Identified ISP: Unknown (Expected: 'Cox Communications')

// Example 4: A data center that's definitely not a home ISP
IP: 203.0.113.10
Identified ISP: DigitalOcean, LLC (Expected: 'Frontier Communications')

I'm trying to figure out if there are common pitfalls when mapping IP addresses to internet providers that I might be overlooking. Are there more reliable data sources or APIs for accurate ISP identification you'd recommend? Or perhaps some debugging strategies to improve the accuracy of the lookup?

Help a brother out please...
