An interesting thing is that if you type in any kind of abracadabra like afsdgdfgs.tk in the browser, the site will open with the appropriate title!
And at
my.dot.tk, you can shorten any links to the form chto-to-tam.tk, and if you have previously entered an abrucadabra in the browser to verify that the domain will be occupied = (
The answer, as it seems to me, is that the DNS server responsible for tk automatically registers the corresponding domain and transfers the server to a single “abracadabra”. I'm right?
