Check your connection, camera, mic, keyboard and screen

When something feels wrong with your internet or your device, the first job is to find out what is actually happening. These free internet and device tests give you the facts in seconds. What is my IP shows your public address and location, the internet speed test measures download, upload and latency, DNS lookup shows the records behind any domain, and IP lookup tells you who owns an address and roughly where it is.

Before a video call or an online exam, the webcam test and mic test confirm that your camera and microphone work and that the browser has permission to use them. The keyboard tester lights up each key as you press it, so a stuck or dead key is obvious, and the CPS test measures how fast you click. For displays, the dead pixel test shows full-screen colours to reveal stuck or dead pixels, the screen resolution checker reports your real pixel size and scaling, and the refresh rate test estimates how many frames per second your monitor is actually showing.

Remote workers, gamers, students sitting online tests, second-hand laptop buyers and anyone on hold with their internet provider use these tools. The device tests run entirely in your browser, and camera and microphone streams are shown only to you and never recorded or sent anywhere. The network tools do go online, but only to fetch the data they need from public services and to transfer test data for the speed measurement.

Reading the results

  • Download and upload speed are measured in megabits per second (Mbps). Video calls need roughly 3 to 4 Mbps each way, HD streaming about 5 Mbps and 4K about 25 Mbps.
  • Latency (ping) is the round-trip time to a server in milliseconds. Under 50 ms is excellent for gaming and calls; several hundred ms causes talking over each other on calls.
  • Public IP is the address the internet sees, usually shared by every device on your Wi-Fi and assigned by your provider. It is not your home address and typically locates you only to a city or region.
  • DNS records map names to servers: A and AAAA records give IP addresses, MX records name mail servers and TXT records hold verification and email security entries such as SPF.
  • Dead versus stuck pixels. A dead pixel stays black on every colour; a stuck pixel shows one colour permanently. Stuck pixels sometimes recover, dead ones do not.

Getting a fair test

  • For the speed test, connect by cable or sit near the router, close downloads and streaming on other devices, and run it two or three times. Wi-Fi speed drops sharply through walls.
  • If the webcam or mic test shows nothing, check that the browser has permission (the padlock icon in the address bar) and that no other app, such as a video call client, is already using the device.
  • Run the dead pixel test in a dark room, and clean the screen first; dust and smudges look like pixel faults.
  • The refresh rate test reads what the browser is delivering, so if a 144 Hz monitor shows 60 Hz, check the display settings in your operating system and the cable you are using.
  • For a support ticket or bug report, my browser info and the user agent parser in our developer tools show exactly what your browser reports.

Internet & Device: frequently asked questions

Why is my IP address location wrong?

IP geolocation works from databases of address blocks, which usually pinpoint the city of your provider’s exchange rather than your street. A VPN, mobile data or a corporate network can place you far from where you really are.

Why is my speed test slower than the plan I pay for?

Advertised speeds are maximums measured at the line, while a test shows what reaches one device after Wi-Fi, other users and the server’s own limits. Test by cable, close other apps and compare several runs before calling your provider.

Is the webcam test recording me?

No. The video is shown in your browser tab so you can see what the camera captures, and it is never recorded, uploaded or stored. Closing the tab turns the camera off.

What is a good ping for gaming?

Under 30 ms is excellent and under 60 ms is comfortable for most online games. Above 100 ms you start to notice delay, and large swings (jitter) matter as much as the average.

How do I find out which DNS records a domain has?

Type the domain into DNS lookup and choose a record type: A for addresses, MX for mail servers, TXT for verification records, NS for name servers or CNAME for aliases. It queries a public resolver and shows the live answer.

Can I test keys that have special functions?

Yes. The keyboard tester shows almost every key, including Shift, Ctrl, Alt, arrows and function keys. A few are intercepted by the operating system or browser, such as the Windows key or certain function keys on laptops, and cannot be tested from a web page.
