IPv6 connectivity test

Check whether your network can reach IPv6 services from the browser.

If IPv6 is unavailable, your network or ISP may not provide IPv6, or it may be blocked by a firewall.

Why run an IPv6 test online

An IPv6 test online helps you confirm whether your current network can reach IPv6 services and whether a public IPv6 address is available in your browser session. It is useful when a website works on one network but not another, when you want to confirm whether your ISP really supports IPv6, or when you are checking the effect of a router change, VPN, proxy, or mobile carrier.

How the test runs

The tool sends a small request from your browser to an IPv6 endpoint and measures whether the response succeeds. If the request returns an IPv6 address, the page shows that public IPv6 address together with a basic browser-level response time. The test runs only while the page is open and does not install anything.

How to interpret results

A successful result means your browser can currently reach an IPv6 service on this network. A failed result usually means IPv6 is unavailable on the connection, filtered by the router or firewall, disabled by the VPN, or not configured by the ISP or mobile carrier. Compare results across Wi‑Fi, ethernet, mobile data, and VPN on or off to isolate where IPv6 breaks.

  • Success with a visible IPv6 address means your browser reached an IPv6 endpoint on the current network.
  • Failure usually means IPv6 is missing, blocked, or unavailable on that path.
  • Different results between Wi‑Fi and mobile data often point to ISP, carrier, or router differences.
  • Different results with VPN on and off often point to VPN filtering, leak protection, or tunnel configuration.

This test reports browser-level IPv6 reachability only. It does not configure dual-stack settings, prove that every app uses IPv6, or diagnose every router, firewall, or ISP policy in detail.

Frequently Asked Questions

What does this IPv6 test online check?

It checks whether your browser can currently reach an IPv6 endpoint and shows a public IPv6 address when one is available. That gives you a quick browser-level answer to whether IPv6 is working on the current network.

How does the IPv6 test work in the browser?

The page makes a small request from your browser to an IPv6-only endpoint and checks whether the request succeeds. If it does, the tool can show an IPv6 address and a basic response time for that browser session.

Why does the IPv6 test fail?

The most common reasons are no IPv6 support from the ISP or carrier, IPv6 disabled on the router, VPN filtering, firewall interference, or a connection that only provides IPv4. Testing on another network helps isolate where the block happens.

Does IPv6 mean my internet is faster?

Not automatically. IPv6 can simplify routing on some networks, but real performance still depends on your ISP, peering, congestion, Wi-Fi quality, and the service you are using. Use speed, ping, and jitter tests to measure actual impact.

Can I run the IPv6 test on mobile data?

Yes. This is a good way to compare mobile data with home Wi-Fi because many carriers and ISPs handle IPv6 differently. If mobile data passes and Wi-Fi fails, the issue is often on the router or home connection.

Does this IPv6 test show my public IPv6 address?

Yes, when the request succeeds and the network exposes one to the browser. That makes the page useful for checking whether IPv6 is active after a router reset, ISP migration, VPN change, or carrier switch.

Why do IPv6 results differ between Wi-Fi, ethernet, and mobile data?

Those paths often use different routers, gateways, ISPs, or carrier policies. A pass on one network and a fail on another usually means IPv6 is available on only part of your setup, not everywhere.

Can a VPN affect my IPv6 test result?

Yes. Some VPNs pass IPv6 traffic, some disable it, and some route or filter it differently. Running the test with the VPN on and off is one of the fastest ways to see whether the VPN changes IPv6 availability.

What does a successful IPv6 result actually confirm?

It confirms that your browser could reach an IPv6 endpoint from the current network during the test. That is useful evidence for support or troubleshooting, but it does not prove every app, game, or device on the network is using IPv6 correctly.

What can this IPv6 test not do?

It cannot enable IPv6 on your router, fix carrier configuration, diagnose every firewall rule, or verify that every destination on the internet is reachable over IPv6. It only checks browser-level reachability to the tested endpoint.

When should I use this IPv6 test online?

Use it after router changes, ISP migrations, VPN changes, dual-stack setup work, mobile carrier comparisons, or when a website or app behaves differently across networks. It gives you a fast first answer before deeper troubleshooting.

Is this IPv6 test safe and private?

Yes. The test runs in the browser, checks network reachability, and does not access personal files. It is meant to answer whether IPv6 works, not to collect unrelated device data.
