I would like to check some websites by using IPv6 only: not only connecting with an IPv6 address but also checking that every other following connection (e.g., for embedded content with iframes) is performed with IPv6.

Is there a browser where I can disable IPv4? Or a proxy I can install?

    One of the key points of the modern network-stack is that higher levels in the stack do not depend on the underlying layer: a web-browser, or any application, is ignorant of the underlying transport protocol and again that is ignorant of the underlying physical medium. This would not be a web-browser option, you would instead configure your network-stack to route everything over IPv6 interfaces.

  • Yes but maybe there is a proxy resolving every DNS query by looking at AAAA records only.

  • I also did not find any way to temporarily disable IPv4 on OS X

  • You'd have to go to your network adapter settings and turn IPv4 off. Nov 10 '15 at 9:42

You can disable IPv4 in your OS and adding some public DNS64/NAT64-Resolver. You can create your own IPv6-only-environment: Apple has prepared such an environment for testing purposes.



Use Firefox Browser! It can be input ipv6 address on URL blank. If you have bookmark made by IPv6 address, Firefox Browser will work on IPv6 address.

  • I am not sure how this answers the question - can you elaborate?

  • Any browser supports the URL with IPv6 addresses, the question is how to force it for every further connection (for example for embedded resources)
