About ISPNet
A free, professional-grade network diagnostic platform built by network engineers — for network engineers, IT professionals, developers, and anyone who needs reliable tools to understand their connection.
Professional Network Diagnostics — Free, Fast, No Account Needed
ISPNet is a comprehensive web-based network diagnostic toolkit designed to give users instant, accurate information about their internet connection, network infrastructure, and domain resources. Every tool runs directly in the browser and communicates with our servers to deliver real measurements — not estimates from a database.
Whether you are an ISP engineer diagnosing a customer's connection, a system administrator troubleshooting routing issues, a developer checking DNS propagation, or a home user trying to understand why their internet is slow — ISPNet has the right tool for you.
All tools are completely free, require no registration, and are built with accuracy and professional usability in mind. We believe powerful network tools should be accessible to everyone.
Democratising Professional Network Tools
The internet is the backbone of modern life. Understanding how it works — and diagnosing when it doesn't — should not require expensive software licences or deep technical expertise. ISPNet was built on the belief that professional-grade network diagnostic capabilities should be freely available to anyone with a browser.
We built ISPNet because we were frustrated with tools that were slow, inaccurate, cluttered with ads, or paywalled behind subscriptions. Every measurement ISPNet produces is a real test performed at the moment you request it. No cached results. No artificial limitations. No accounts required.
ISPNet is a product of Tiidon Innovations Limited, a technology company focused on building practical, high-quality software products and tools. We develop solutions that solve real-world problems with a focus on reliability, performance and accessibility.
Our team comprises software engineers and network specialists who use these tools in their own daily work. ISPNet is built from the ground up using the standards and accuracy requirements we hold ourselves to professionally.
We are committed to keeping ISPNet free, continuously improving its accuracy, and adding new tools based on community feedback.
How Our Measurements Work
Speed Test: Uses parallel HTTP streams to measure throughput. Download is measured by fetching random binary data from our server; upload by posting data back. Results reflect the connection between your device and our server — not the theoretical maximum of your line.
Ping & Traceroute: Server-side ICMP tools run from our infrastructure to your target host. These reflect network conditions between our server and the destination, which is useful for diagnosing routing issues independent of your local connection.
DNS Lookup: Queries are made from our server using PHP's native DNS resolution, backed by shell dig where available. Results reflect what our authoritative resolvers return at that moment.
Geolocation: IP geolocation data is sourced from ip-api.com and is approximate. City-level accuracy varies by region and ISP.
All measurements are provided as-is for diagnostic and informational purposes. No data from your tests is stored on our servers.
