I am trying to understand something about DNS that seems too simple but I could not find anything related to this in particular.
When I buy a domain name (example.com) I specify DNS servers with the registrar (ns1,ns2.example.com). When someone is looking to resolve anything related to example.com, I presume that at the registrar level, they are directed to the Nameservers I specified with the registrar.
My question is, if the primary nameserver I were to put down was ns1.example.com (at my purchased domain), how does anything resolve, as that seems like it puts any request in to a recursive loop back to itself? I did not notice anywhere actually having to put in an IP address (other then on my nameserver which - how did the request get there in the first place)
Where am I going wrong with my reasoning?
