About NetworkCheck

NetworkCheck.net is a simple set of free browser-based tools for checking internet speed, public IP information, and basic website status.

The site is built for normal users who want a quick answer without downloading an app, creating an account, or digging through technical settings. The tools are intentionally focused: test your connection, see your public IP address, or check whether a domain appears reachable.

NetworkCheck is also a growing library of plain-English troubleshooting guides. The goal is to help people understand what the numbers mean, what to try next, and when it makes sense to contact an internet provider or website owner.

What the tools do

• Internet Speed Test: Measures download speed, upload speed, and ping from your browser.
• What Is My IP Address: Shows your public IP address and approximate connection details.
• Is This Website Down: Performs a basic DNS-based check to help determine whether a domain is resolving.

What the tools do not do

NetworkCheck does not replace a full network monitoring platform, provider diagnostics, or professional IT troubleshooting. Results can vary based on browser, device, Wi-Fi signal, VPN usage, location, and third-party services.
