Network Monitor

Watch your internet connection in the browser, no terminal needed. Detects drops in real time and logs uptime, latency, and how long each outage lasted.

NetworkTest
Network tools diagnose your internet connection: what your public IP address and ISP are, how fast your connection actually is, and whether it has been dropping out. A public IP address is the address your ISP assigns to your connection that websites and other services see, distinct from the private IP address your router hands out to devices on your home network, which is why it changes when you switch networks or your ISP reassigns it. They are used by anyone troubleshooting a slow or flaky connection, checking what a website sees as their location before using a service with regional restrictions, or confirming their ISP is delivering the speed they are paying for. A concrete example: someone whose video calls keep freezing runs the network monitor to log drops and latency over an hour, producing evidence that is more useful to an ISP's support line than just saying it is laggy. None of these tools require installing software; they run in the browser and report public network information only.

Frequently Asked Questions

What is the difference between IP Address Lookup and Internet Speed Test?▾
IP Address Lookup shows your public IP address, ISP, and approximate location. Internet Speed Test measures your actual download and upload speed, plus ping and jitter.
Can Network Monitor tell me why my connection keeps dropping?▾
It logs uptime, latency, and how long each outage lasted, which is useful evidence for an ISP support call, though it doesn't diagnose the underlying cause.
Are these Network Tools tools free to use?▾
Yes, all 4 tools in this category are completely free. No sign-up, no account, and no payment required. Every tool works instantly in your browser.
Do these tools work on mobile phones?▾
Yes. All tools are mobile-responsive and work on iOS, Android, and desktop browsers. Touch events are supported where applicable.
Is my data sent to a server?▾
It depends on the tool, so each tool page says which it is. Most run entirely in your browser and send nothing. Some fetch public data to work, such as price charts and currency rates. A few, like the dynamic QR generator, need an account and store what you create, because that is the feature.
