I have a working website but when I go back to the "DNS Manager" to add an Alias 'www" there is nothing there.  The "Forward Lookup Zone" is empty.  I can type "mysite.com" into any browser in the world and I can view my site but there is nothing in "DNS Manager".  Where did all the data go?

Hi Philosophiae,

When the website is published to internet, the corrseponding records are registered in public DNS servers. So that users could browse it from all over the world.

To add Alias in our own DNS server, we could create a Host record first. To use own DNS server to resolve queries, we need to configure the IP address of the server as DNS server on clients.

Here is the reference for DNS records:
