Cool, thanks for finding that. And thank you, Stefan!

I wonder how they managed to get such a short domain name, I thought 3 characters was the minimum. And it must cost quite a lot.

It's actually easy to get a 2 character name if you are willing to use an obscure tld.

I own http://0k.nu and I just regularly registered it.

I also own http://π.pw and http://ಠ.com .

There's a lot of 2-letter domains: https://en.wikipedia.org/wiki/Single-letter_second-level_dom...

Single-letter domains for .org, .net, and .com are/were reserved, although there are exceptions such as http://www.x.org. Other TLDs may vary.

For those who are looking for short domains .SE is selling a few at the moment. http://www.tradera.com/campaign/punktse

The minimum is 1 character excluding the TLD. Like Twitter has http://t.co

Actually even zero character ones exist http://uz/

It only works for me (OS X, Safari) when written as http://uz./ (a proper FQDN)

That isn't a zero character name. It's just the TLD itself acting as a website. It's a 1 label domain rather than the usual 2-3 labels.

Well, I suppose the root counts as a zero-character domain.

The trailing . makes it fully-qualified.

It does not resolve here.

Interesting side-effect, windows doesn't support TLD-only addresses.

.monash used to also have the same property (if I am not mistaken), until they realized this fact, I imagine.

I'd be pretty interested to see how much a domain like this would sell for...

They list the owner in the legal information page: http://dns.js.org/legals.html

Thats my brothers homepage/business. He helped mé with the design and asked me for the backlink.

A few others have already responded, the sites whois entry also names Stefan Keim.
