install the control panel on a fault-tolerant virtual or dedicated server. You can install DNSmanager together with BILLmanager, VMmanager or DCImanager.


You must not install DNSmanager and ISPmanager on a single server.

We don't recommend installing DNSmanager on the same server with IPmanager.

Minimum system requirements

  • CPU: 1 GHz;
  • Kernel: 1;
  • RAM: 2 Gb;
  • HDD: 10 Gb in the root directory.

Recommended system requirements 

  • CPU: 2 GHz;
  • Kernel: 2;
  • RAM: 4 Gb;
  • HDD: 20 Gb in the root directory.

Operating system

  • CentOS 7 x64 (recommended).


You should install a minimal version of the operating system.

Do not upgrade the operating system to a major version on the server where the control panel is installed.

We strongly recommend a clean install of DNSmanager. All the services that DNSmanager requires, will be installed automatically during software installation. 

We don't recommend that you install the software product from a third-party repository.

  • 22/TCP — for SSH;
