Frequently Asked Questions
Is this ISP lookup tool really free to use without limitations?
Yes, our Advanced What is My ISP Tool is completely free for unlimited use. We utilize publicly available IP geolocation services and browser APIs to provide this service at no cost, with no usage restrictions or account requirements.
How accurate is the ISP information provided by this tool?
Our tool provides highly accurate ISP information by querying multiple IP geolocation databases. However, accuracy may vary based on database freshness and the complexity of network routing. For most users, the information is sufficiently accurate for general purposes.
Will this tool work if I'm using a VPN?
If you're using a VPN, the tool will detect the VPN provider as your ISP rather than your actual internet service provider. This is because VPNs route your traffic through their servers, masking your real IP address and ISP information.
