To all who can't replicate it: Clicking a link, copy/pasting the URL, and typing it from the keyboard all behave differently. Make sure that you manually type

    http://ai/

into the location bar (do not use https). Also try with and without the trailing slash.

Safari on macOS will not load this address. It does resolve, weirdly, "host" in the Terminal works and I can see Safari's requests being answered by my home DNS server in the logs.

But Safari just throws an error: Can't connect to the server "ai".

Update: It works if you include a trailing dot: http://ai.

Update 2: HN's URL parser does not include the dot in the hyperlink. Frustrating.

http://ai. Works in safari for iOS, shockingly.

[LeoPanthera]

Huh. It does not work on my iPhone. Same error. I wonder what the difference is.

The link didn't include it, but try again with the trailing '.' period

[LeoPanthera]

Aha, yes, this works.

[selcuka]

Weird. `dig` on macOS does not resolve it but `host` does.

[LeoPanthera]

That's interesting. dig works for me.

I suspect all these difference depend on what DNS server you are using.

The proper URI should be "http://ai." (with the ending dot)
