What prevents inserting a taken domain name to cloud-based dns system
<p>Easy question about how dns works.</p>

<p>In simple form: What prevents inserting a taken domain name to a dns system?</p>

<p>Let's take an example:</p>

<p>I have bought a domain from domain registrar, let's pretend it's example.com.</p>

<p>Then I have a website at ip EXAMPLE_IP. For that app, I have cloudbased DNS system, where I have put dns record for example.com to match EXAMPLE_IP. Which means all requests to that domain will find their way to my website.</p>

<p>Now what would prevent someone to use that same example.com in some other dns system, and point it to some other website? What I don't yet know is where does the ownerhsip query of a domain name occur?</p>

<p>Please don't close, I just want to understand.</p>
