Using the Enterramon IPv6 Test
What is the IPv6 Test
Most connection tests ask you to type in a target. This one doesn’t. It measures the connection you are using right now to read this page, because that’s usually what people actually want to know when they search for “do i have ipv6” or “is ipv6 enabled.”
We hit five regions from your browser. South Africa, Germany, the United States, Singapore, and Australia. For each region we try three separate hostnames. One only answers over IPv4, one only over IPv6, and one accepts both. Which of those respond tells us what your connection can actually reach.
Using the Enterramon IPv6 Test
Head to enterramon.com/tools/ipv6-test and hit Run Test.
There is nothing to type. The tool warms up connections to our global probe network and then runs a series of timed fetches against each region. If your device has no IPv6 route at all, the probe fails fast. The operating system refuses the connection immediately because there’s nowhere to send it.
If the probe times out, that’s a different story. It means your device tried to connect and sat there waiting for an answer that never came. Something on your network advertised IPv6 capability but can’t actually route it to the internet. We treat that timeout as a legitimate diagnostic signal rather than an error.
Understanding the results
Verdict
Whether your connection is Dual Stack (both protocols work), IPv4 Only, or IPv6 Only. Dual stack is the standard for most modern residential and mobile networks. IPv4 only means your ISP, router, or operating system isn’t giving you IPv6. Nothing is broken, but you are relying on a protocol that ran out of addresses in 2011.
Browser Preferred
Which protocol your browser chose when both were available. Browsers use Happy Eyeballs (RFC 8305) to race an IPv4 and an IPv6 connection and pick the winner. If you’re dual stack but your browser consistently picks IPv4, something on your IPv6 path is slow enough to lose that race.
Regional Latency
A table showing the round-trip time for both families across five regions. Absolute latency is dominated by distance, so the per-region difference is the signal. A consistent penalty across all regions usually points to a tunnelled deployment or a misconfigured border router close to your network.
Network Identity
The ASN and country of the network you are connecting from. This helps confirm whether you are testing from your home connection, a mobile network, or a corporate proxy.
How an IPv6 test can help you
Having IPv6 and using IPv6 are two different things. A lot of site owners assume their connection is healthy because they see an IPv6 address in their settings, but if the browser never actually picks it, the path is likely slower or less stable than it should be.
The regional table catches problems that a single-endpoint test misses. If IPv6 fails to every region, the problem is on your end. If it works for some regions but not others, the issue is likely in transit or peering between your ISP and those specific destinations. IPv6 routes are arranged separately from IPv4, so a path to one destination can be missing or broken while IPv4 to the identical server is healthy.
And the timeout diagnosis saves you from chasing ghosts. Disabling IPv6 makes the symptom of a hanging browser go away, which is why the advice spreads, but it leaves the misconfiguration in place. Knowing whether your device is refusing the connection or just timing out tells you whether to look at your router settings or call your ISP.
What an IPv6 test is not
This is a connectivity and latency probe, not a throughput test. It doesn’t measure how fast you can download a large file over IPv6 versus IPv4. A meaningful throughput test needs a multi-second sustained transfer and would tell you more about your last mile than about the IPv6 protocol itself.
It also isn’t a full network audit. It checks reachability and preference from your browser to our probes. It doesn’t check your local DNS server configuration, your router’s prefix delegation status, or whether your firewall is blocking specific ICMP packets. Our [Global Statistics](/global-statistics/) page tracks IPv6 adoption by country and network if you want to see whether your provider is among those offering it.
If you want to know why a specific website is slow, that’s a different kind of test entirely. The [Ping Test](/tools/ping-test/) can help isolate whether the latency difference is consistent or intermittent, and the [Traceroute](/tools/traceroute/) tool maps the actual path each protocol takes to identify where the divergence happens.
