ISPmanager can configure name servers (DNS).
You need two IP addresses for name servers. Even better if these are two different servers; however, NS can also be located on one server.
The easiest way to set up DNS is using registrar name servers. This procedure doesn’t require any additional configurations on the server.
If your registrar doesn’t provide name servers, you can simply configure them in ISPmanager. You can do it with a few methods:
The most reliable DNS system can be achieved with ISPmanager master server and two DNSmanager slave servers.
In this case, name servers are located on different physical servers, guaranteeing high availability of domain names.
