What is an ISP Checker?

An ISP Checker is a tool that helps users identify their internet service provider. By analyzing your IP address, network metadata, and other connection details, it instantly reveals who is providing your internet access. Whether you're troubleshooting network issues, verifying your VPN, or checking service consistency, an ISP lookup tool is essential.

How the ISP Checker Works

The ISP lookup tool functions by analyzing the public IP address of your current internet connection. It queries a global ISP database, which contains mappings of IP ranges to known providers. The returned result includes your ISP name, IP address, location, and in some cases, the type of connection such as fiber, DSL, or mobile.

Frequently Asked Questions (FAQs)

What is an ISP?

An ISP (Internet Service Provider) is the company that provides your internet access, whether through broadband, fiber, satellite, or mobile networks.

Is this ISP checker free?

Yes, our free ISP checker is 100% free to use with no sign-up or subscription needed.

Does this tool store any data?

Can I use it on mobile?

Will it show if I’m using a VPN?

Yes. If you're connected to a VPN, the ISP shown will be that of your VPN provider, not your actual ISP.

Can I check someone else's ISP?

No. The tool only detects the ISP of the current device making the request—it cannot look up others' IPs remotely.

What does dynamic vs static IP mean in this context?

Dynamic IPs change regularly and may result in different ISP or location displays. Static IPs stay constant and are easier to map consistently.
