Check whether your internet connection can reach an IPv6-only server using our free IPv6 Connectivity Test. Run the test directly in your browser without installing software or entering your IP address.
This test checks IPv6 reachability on your current connection. It does not measure internet speed or guarantee that your internet service provider offers native IPv6.
Find out whether this website sees an IPv4 or IPv6 connection. A full IPv6-only reachability check is not yet configured. No speed measurements or IP address display. Click the button to check the connection seen by this website. An optional IPv6-only browser test runs when available. The connection protocol seen by the website may belong to a reverse proxy or CDN, not your browser. Seeing IPv4 does not mean IPv6 is unavailable. Only a successful test against a genuine IPv6-only endpoint confirms IPv6 reachability to that destination, possibly through a VPN or proxy.Check your connection protocol
How to Check Your IPv6 Connectivity
Click the Run IPv6 Test button above. The tool first checks whether its own test service is responding, then attempts to reach a specially configured IPv6-only destination.
Your results will appear on the screen. You can select Run Test Again to repeat the check, particularly after changing your network or router settings.
Understanding Your IPv6 Test Results
| Test result | What it means |
|---|---|
| IPv6 reachability confirmed | Your browser successfully reached the configured IPv6-only destination. |
| IPv6 could not be confirmed | The IPv6-only request failed. Your connection, browser settings, or the test endpoint may be responsible. |
| Test could not start | The website’s test service did not respond correctly, so IPv6 was not tested. |
| Test not available yet | The website’s IPv6 testing endpoint has not been fully configured. |
A successful result confirms reachability to the specific test destination. An unsuccessful result does not automatically mean IPv6 is disabled on your connection.
What Is IPv6?
IPv6 stands for Internet Protocol version 6. It is a networking protocol that enables devices to communicate across IP networks.
IPv4 uses 32-bit addresses, while IPv6 uses 128-bit addresses, providing a much larger address space.
Many networks use IPv4 and IPv6 together, a configuration known as dual stack. A device may also reach certain services through a VPN or other network translation system.
Having an IPv6 address in your device settings does not necessarily mean you can access websites over IPv6. For example, a link-local IPv6 address beginning with fe80:: is used for communication on the local network and does not establish public internet connectivity.
How Our IPv6 Connectivity Test Works
The NetTools Pakistan IPv6 checker uses a browser-based connection test.
First, it requests a small image from this website to confirm that the test service can respond. Next, it attempts to load a similar image from a separate hostname configured for IPv6-only access.
That hostname must have an IPv6 AAAA DNS record without an IPv4 fallback. DNS, or Domain Name System, helps browsers locate servers by translating hostnames into network addresses.
If the browser successfully loads the image from the IPv6-only destination, the tool reports successful IPv6 reachability.
What this test does not measure: download speed, upload speed, latency, packet loss, public IP address, or the quality of your entire internet connection.
Why Is My IPv6 Connectivity Test Failing?
A failed IPv6 check can have several causes. Your internet provider may not be offering IPv6 on that connection, your router may not be configured for it, or a browser or network restriction may be blocking the request.
Try these steps:
- Check your internet connection. Make sure ordinary websites load properly before repeating the test.
- Try another network. Compare your home Wi-Fi connection with mobile data to see whether the results differ.
- Check your VPN or proxy. If you use one, its routing may affect the result. Temporarily disconnect only if appropriate and safe.
- Check your router settings. Look for an IPv6 configuration option, but avoid changing unfamiliar settings without your provider’s guidance.
- Try another browser. Browser extensions, security settings, or image blocking can interfere with the test.
- Ask your ISP. If IPv6 remains unavailable, ask whether your subscription and local network support it.
If the tool reports that the test service is unavailable, the problem may be with the testing endpoint rather than your internet connection.
Does PTCL Internet Support IPv6?
IPv6 availability on a PTCL connection needs to be confirmed for the specific service and network configuration. It should not be assumed from your package name, advertised speed, or whether you use DSL or fiber.
The same applies to other internet providers in Pakistan.
If your IPv6 test fails, contact your provider to confirm whether IPv6 is supported for your connection and whether additional router configuration is required.
Is IPv6 Faster Than IPv4?
IPv6 does not automatically make your internet connection faster.
Actual performance depends on routing, network congestion, equipment, server location, and other conditions. Some destinations may perform better over one protocol than the other.
This IPv6 Connectivity Test checks whether a connection succeeds. It is not designed to compare IPv4 and IPv6 performance.
For download speed, upload speed, and latency measurements, use a dedicated internet speed test.
Is This IPv6 Test Safe to Use?
The test does not require your router password, ISP account details, or manual entry of an IP address.
It makes small image requests to the website’s testing service and its configured IPv6-only destination. These requests may appear in normal web-server or hosting logs.
The test does not inspect your private network, change your router settings, or scan connected devices.
Check Your IPv6 Connection Again
Your result can change when you switch between Wi-Fi and mobile data, enable or disable a VPN, or connect through a different router or internet provider.
Run the test again after making a relevant change. Compare the results, and contact your ISP if you need confirmation of native IPv6 availability on your connection.
