Webhost Manager ​
The Webhost Manager page allows resellers to configure the nameservers their end-users will use for their domains.

Overview ​
URL: /reseller/webhost-manager
The page contains a Nameservers section with the description: "Configure the nameservers your end-users will use for their domains."
Nameserver Source ​
A radio button selection allows choosing between two nameserver modes:
Root Nameservers ​
Uses the system default nameservers, automatically configured based on the hosting server's hostname and IP. The section shows both of them: the primary and the secondary system nameserver. Before panel 1.9.4, both fields showed the first nameserver.
Custom Nameservers ​
Allows resellers to define their own branded nameservers (e.g., ns1.yourdomain.com, ns2.yourdomain.com). When selected, two fields appear: Nameserver 1 and Nameserver 2. Both are required, each must start with ns and have at least three labels, and the two must be different names. Letter case and a trailing dot do not make a name different.
Save Settings ​
Click Save Settings to apply the chosen nameserver configuration. This setting affects all newly created domains under the reseller's accounts.
Over the API ​
Since panel 1.9.4, GET and PATCH /api/reseller/settings on the reseller REST API read and change the same settings, with the same checks. See Beyond billing.
