Review on Quad9 by Mike Snedeker

I like the fact that it's easy to setup and very simple to use. It does not offer much in terms of customization - you can't really do anything with it other than what is provided by the software itself. You can't add your own domains or change the DNS records themselves. This is a very basic tool for anyone who needs a DNS server. The price is also pretty steep. Not sure if this is because we are using it as a business solution, but it would be nice to have more control over our DNS records. We're solving the issue of having multiple domain names pointing to one IP address.
