> That's not how .nyc is used or is expected to be used. It's a top-level domain, not a dotless host name.

While it is prohibited by the ICANN policy [1], it is not strictly enforced so that there are multiple TLDs with A/AAAA records. They traditionally could be resolved with a trailing dot (thus it is not a dotless host name, that would have no dot), but nowadays many browsers refuse to resolve them without an explicit scheme. But they do still exist: try `http://pn./` for example.

This prohibition only applies to gTLDs. It does not apply to ccTLDs.

Aha, thank you for pointing it out---I actually overlooked a very informational RFC that says exactly this [1].

http://ai./ is a better example.

both pn and ai are giving me DNS errors in chrome on ubuntu.

The DNS server at work (which I maintain... oops) doesn't work, but home and other servers do work:

  host ai. 1.1.1.1
  Using domain server:
  Name: 1.1.1.1
  Address: 1.1.1.1#53
  Aliases:
  
  ai has address 209.59.119.34
  ai mail is handled by 10 mail.offshore.ai.

HN doesn't like your link's formatting. Try: http://www.pn./ or http://www.pn/

This unintentionally makes a point about how hard these domains are to use; they're not supported very well.

[LukeShu]

The problem is the closing ` is being treated as part of the URL.

Your .pn link doesn't work for me without www part.

At least for https://www.fi/ the case is that someone registered "www" as the domain name in the early days.

[lifthrasiir]

Hmm, I guess the current browsers simply don't like such domain and automatically put www. At the very least, the Google DNS gives the following:

    ai. 209.59.119.34
    cm. 195.24.205.60
    dk. 193.163.102.58
    gg. 87.117.196.80
    je. 87.117.196.80
    pn. 80.68.93.100
    tk. 217.119.57.22
    uz. 91.212.89.8
    ws. 64.70.19.33

But I agree that these domains are now out of luck, given that browsers no longer even remotely support them.

I see that the Vatican has given up. Long ago, http://va/ was it. No other name under va existed. Netscape Navigator was able to navigate to that part of the net.

It really did make sense for such a tiny place.
