Frequently Asked Questions

Your IP (Internet Protocol) address is a unique label assigned to your device by your Internet Service Provider (ISP). It identifies your device on the internet, similar to a home address. There are two types: IPv4 (e.g. 192.168.1.1) and the newer IPv6 format.

Yes. When you visit any website, your IP address is visible to that server — it's how the internet knows where to send data back to you. This is completely normal and technically unavoidable without using a VPN or proxy.

Yes. A VPN (Virtual Private Network) routes your traffic through a VPN server, so websites see the VPN's IP address instead of yours. Our site can still detect if you're using a proxy or datacenter IP address.

Yes. IPv4 addresses look like 192.168.1.1 (32-bit, about 4 billion addresses). IPv6 looks like 2001:db8::1 (128-bit, virtually unlimited addresses). IPv6 was created because the world is running out of IPv4 addresses.

WHOIS is a protocol that lets you look up registration information for a domain name or IP address, including the owner, registrar, creation date, expiry date, and nameservers. It's useful for finding out who owns a domain or when it was registered.

DNS (Domain Name System) records map domain names to IP addresses and configure other services. A records point to IPv4 addresses, AAAA to IPv6, MX to mail servers, NS to nameservers, TXT for verification, and CNAME for aliases.

Our speed test measures real-world HTTP throughput to our server, which closely reflects actual browsing and streaming speeds. For best accuracy: close other apps, disable VPNs, run 3 tests and average the results. Wired connections give more consistent results than Wi-Fi.

Yes. We use the browser's built-in Web Crypto API (crypto.getRandomValues) which is cryptographically secure. Passwords are generated entirely in your browser — nothing is ever sent to our servers.

Make sure your browser has microphone permission (click the padlock icon in the address bar). Check that your mic isn't muted in system settings. Try Chrome or Firefox for best WebAudio support. Some corporate networks block microphone access.

A dead pixel is a pixel on your screen that no longer lights up — it appears permanently black. A stuck pixel is one stuck on a single color (often red, green, or blue). Our screen test helps you spot these by displaying solid color panels full-screen.

Our keyboard test lights up every key you press. If a key doesn't light up when pressed, it may be defective. Ghosting is when multiple simultaneous key presses are not registered correctly — common in cheaper keyboards.

The share link contains a snapshot of your IP address, geolocation data, and basic device info (OS, browser, screen size) at the time of creation. Links expire automatically after 7 days and no personally identifiable data is permanently stored.

We temporarily display recent visitor IPs on the homepage as a convenience feature, but we do not store your personal IP data linked to an identity. Our platform follows a no-log policy for personal data.

Use our WHOIS & Domain Lookup tool. Enter the domain name and select "Availability" from the dropdown. We perform a live DNS and WHOIS check to determine if the domain is registered or available.

Download speed measures how fast data comes from the internet to your device — important for streaming, browsing, and gaming. Upload speed measures how fast data goes from your device to the internet — important for video calls, file uploads, and cloud backups.

Ping (latency) measures the time in milliseconds for a signal to travel from your device to a server and back. Lower ping = faster response. It's critical for gaming (aim for under 50ms), video calls, and real-time applications.

Yes! Our speaker test uses the Web Audio API built into modern browsers. No plugins, Flash, or downloads required. You can test left/right channels, generate tones at any frequency, and run a full frequency sweep.
