If you own a DNS zone you need to have that hosted somewhere in a datacenter.
So say you own example.com you need to have a server (but usually a more redundant setup) that is queried for everything regarding that: which ip(s) is www.example.com, where does the mail go, some other settings (time to live), all subdomains, text records (various purposes).
Ah, no worries! It’s purely about DNS!
