You might be able to access it if you have an Apple device and Private Relay enabled. I only have IPv4 at home and was surprised to see an IPv6 address when I typed in "what is my ip" into Google. For the most part, Private Relay works pretty good.

Maybe the solution for more IPv6 adoption is for tech giants like Apple, Google, Microsoft to make proxies like Private Relay ubiquitous on every device/browser.
