Test-IPv6
Test-IPv6 checks whether a browser and network connection can reach IPv6 resources.
About Test-IPv6
Test-IPv6 checks whether a browser and network connection can reach IPv6 resources, and shows the current IPv4 and IPv6 addresses. It works by instructing the browser to request a series of test URLs. Each URL is set up to use a particular combination of IPv4 and IPv6 DNS records, and the combined pass and fail results indicate how ready the browser and connection are for websites that publish IPv6 addresses.
The site requires JavaScript and the ability to load cross-site scripts to run the tests. If a browser extension such as NoScript blocks these, the test cannot complete, and the site notes that users may need to temporarily allow the page. A simpler test option gives a quick pass or fail for IPv4, IPv4 plus IPv6, and IPv6, but it provides little diagnostic detail. The site also has a form for sending test results and questions to the site administrator. That form includes the user's IP address.
Key features
- Tests browser reachability of IPv4-only, IPv6-only, and dual-stack DNS test URLs
- Displays the current IPv4 and IPv6 addresses
- Runs large-packet tests over dual-stack and IPv6 connections
- Checks whether the ISP's DNS server can reach IPv6-only DNS servers
- Attempts to identify IPv4 and IPv6 service providers for the connection
- Offers a simple pass or fail test with less diagnostic detail
Best for: Home users and support staff who want to check whether a browser and network connection are ready for IPv6 websites and need a breakdown of which tests failed.
Good for
- Each test lists the URL used and a description of what it is designed to check
- Includes a simple pass or fail option for users who want a quick result
- Attempts to identify IPv4 and IPv6 providers, which may help with diagnosis
Watch out for
- Requires JavaScript and cross-site scripts, so script blockers can prevent the tests from running
- The simple test offers little diagnostic information
- The results form includes the user's IP address, which is shared with the site administrator

Test-IPv6 FAQ
Why does the test need JavaScript?
The site states that JavaScript and the ability to pull in cross-site scripts are required to perform the testing. If JavaScript is disabled by an extension or browser setting, a message will remain on the page.
What is the difference between the full test and the simple test?
The simple test gives a quick pass or fail for IPv4, IPv4 plus IPv6, and IPv6. The site notes that it offers little diagnostic information, while the full test shows results for each individual URL.
Is my IP address shared when I use the results form?
The site states that the form includes your IP address, which is shared with the site administrator so that questions can be answered. The site also states that using the form implies consent.
