What is the benefit of using Digital Ocean's DNS over your registrar's default DNS ?
When you register a demain, you can bind it to a specific IP address in the interface of your registrar. For example, you can bind example.com for it to be resolved as your DO's droplet IP address.
So, what is the benefit redirecting your registrar's DNS to DO ones ? Isn't it slower ? etc, what is the point of all of this ?
