How to park a domain cpanel
<p>I have a website with a name I don't really like. How do I change it? I read online that this process is called "domain parking" but didn't really understand how it works. I have seen the option to add a parking domain in my cpanel but if I just input the name I want my domain to have it tells me:</p>

<p>"Could not determine the nameserver IP addresses for “[domain name I tried to input]”. Please make sure that the domain is registered with a valid domain registrar.
"</p>

<p>I have no idea what this means or what a "registrar" is. I googled extensively and I saw a lot of similar stuff but nothing clear enough like a tutorial and that's what I need a "click here, then click here.." kind of tutorial. I know little of servers, whm, cpanel and all that stuff. Just want to change the domain name :)</p>
