DNS Manager in the Admin panel is used to create and manage:
- service DNS zones - to host your corporate site and provide third level domain hosting.
- instant alias templates - to provide immediate access to users' newly registered domains until their domain's DNS hasn't been propagated.
- DNS records - to manage servers external to Parallels H-Sphere with Parallels H-Sphere DNS.
It's not intended to work with your user domains' dns.
