In scenarios where internal DNS server does not exist, can we skip putting
internal DNS while setting up the zone? Does cloudstack enforce to use
internal DNS?

When creating a new zone, I have to enter the address for Internal DNS

"Internal DNS 1 and Internal DNS 2. These are DNS servers for use by
system VMs in the zone (these are VMs used by CloudStack itself, such
as virtual routers, console proxies, and Secondary Storage VMs.).”
The internal DNS server is usually the corporate DNS servers that
provide “internal” DNS services for your LAN. Usually, these are RFC1918 IPs
which is why its hosted “internally”.
Question 1: Who manages the Internal DNS? Is an Internal DNS server
setup and managed by me, or is it setup and managed by Cloudstack?
You (or your IT team).
Question 2: If Internal DNS is setup and managed by me, how should it be
setup?
set it up any way you look. As long as the internal DNS server can
resolve the hostname to IP addresses, you should be fine.
Question 3: If it is setup and managed by Cloudstack, when did it get
setup, and how can I find out what address Cloudstack is using for
this server?
Its not managed by cloudstack. Most of the time, your internal and
external DNS settings would be your corporate DNS server.
If a public DNS server can resolve IP addresses for hosts in your LAN,
you can use any public DNS server as your internal and external DNS
resolver.
Hope that makes sense.
