If a server has only IPv6 addresses without a domain name, how can I connect to the server from my web-browser?


According to RFC2732, literal IPv6 addresses should be put inside square brackets in URLs, e.g. like this:


If you also need to specify a port other then 80 to access the server it has to be placed after the closing bracket:


Of course, you have to have end-to-end IPv6 connectivity to that host. E.g. if the server is not inside your own local network, you need to have IPv6 connectivity, either via your ISP (rare), or via some kind of IPv6 in IPv4 encapsulation (tunnel).

    this doesn't work in google chrome if you use link local addresses (with the %eth0 suffix). – anarcat Dec 8 '15 at 0:56
  • does this work for a domain? – Jason Sebring Mar 17 '17 at 1:18

    If your ISP does not support IPv6, an SSH tunnel can be used to access IPv6-only websites by connecting to the IPv4 address of a VPS that also supports IPv6: ssh -fND 1080 x.x.x.x. You can then connect to the proxy localhost:1080 in your web browser. – baptx Jun 14 '19 at 15:26

  • This seemed to work for localhost, i.e. [::1]:3000, but not a different computer on the same network, on either Firefox or Chrome. I can connect to the other server in-browser with the IPv4 address, and I can ping the other device with ping6. Both servers have the same exact content, if that matters. – trysis Jul 18 '20 at 12:43

Put the ipv6 address into your browser address bar like you would a dns name or an IPv4 address, except enclosed in square brackets:


(example with localhost)

This is supported in Chrome, Firefox, IE and probably other browsers.

Note that you need to have IPv6 working on your OS, and every device in the path to the destination (including proxy servers if you use one).

  • don't forget to start a web server before testing localhost – baptx Jun 14 '19 at 14:43

If required to test locally with IPv6, put below AAA Record in address bar


will be equivalent to write


or below IPv4 A (Host) Record
