I wonder what Elon paid for x.com?

  I'm not sure. There was a short period when you could register one letter dotcoms before about 1994. He's owned it since forever that I know of. His first company was called X, which became PayPal. I spent a long time in the mid-90s trying to persuade INTERNIC to let me register b.com.

    Shame. That would have made a great Chinese porn site. https://en.wiktionary.org/wiki/%e5%b1%84 https://en.wiktionary.org/wiki/%e5%b1%84

      I'm pretty certain you can register one-letter IDN .coms. I registered a bunch the day the IDN system went live, and I had no idea what characters I was registering or what they meant and I later let them all lapse.

    See about a dozen comments in this thread, PayPal owned it post-acquisition until 2017 when Musk bought it back.

    What's that all about then? I'd expect curl to deal with either/or curl should especially live with a punycode version. Unless the punycode from the OP is incorrect? From basic online tools, it looks like it simply converts to x.com

Are you sure? When I type https://xn--971h.com https://xn--971h.com in it doesn't work, but clicking the link in your comment does because HN has made the href x.com. The browser converts 𝕏.com to x.com before going there too. Moreover, X and 𝕏 are treated as equivalent characters in this context, so whois 𝕏.com looks up x.com, and 𝕏.com's punycode encoding is x.com: https://www.whatsmydns.net/idn-punycode-converter?q=%F0%9D%95%8F.com https://www.whatsmydns.net/idn-punycode-converter?q=%F0%9D%9... whois xn--971h.com returns the same thing as an unregistered domain.

  HN automatically converts these urls to punycode, maybe this is a bug and it automatically converts everything to punycode even though it doesn't make sense?
  - mkl 3y ago
    I think so. Then I'm not right about the punycode encoding of 𝕏.com - it's that it isn't even needed. I've emailed dang about it.
  - yreg 3y ago
    It's unrelated to HN. Copy pasting 𝕏.com into the address bar still leads to x.com related: https://en.wikipedia.org/wiki/IDN_homograph_attack https://en.wikipedia.org/wiki/IDN_homograph_attack
    - mkl 3y ago
      I already mentioned that, and it's not what they mean. Hover your mouse over a https://xn--971h.com https://xn--971h.com link in a comment on HN and notice that it's pointing to https://x.com https://x.com. This does seem to be an HN thing; see here: https://jsfiddle.net/rtfhejdy/ https://jsfiddle.net/rtfhejdy/

  Looks like it's also not possible to register xn--971h.com (I tried both Namecheap and Cloudflare).

Also https://х.com https://xn--u1a.com is for sale (where х is a Cyrillic letter, see [0]). Would be funny to buy it and make a redirect to threads.net. [0] https://en.wikipedia.org/wiki/Kha_(Cyrillic) https://en.wikipedia.org/wiki/Kha_(Cyrillic)
