Scenario: You buy domain abc.com from provider XYZ.
You want to host your own DNS server on example.com
(on ns1.example.com ns2.example.com). The domain and both subdomains will point to same IP.
XYZ allows you to create some "magic" entries where you say
ns1.example.com and ns2.example.com are name servers and point to those IPs.
My question is if you host your own DNS server how can the domain provider (XYZ) provide those 2 "magic" entries ?
