Appearance

Nameserver Selection ​

Nameserver Selection decides whether this server answers DNS queries itself, or leaves DNS to someone else.

Nameserver Selection

Overview ​

URL: /admin/settings/nameserver-selection

The page is reached by its address; it is not listed in the sidebar.

A nameserver maps domain names to addresses. Without one answering for a domain, nothing that depends on that name works: no website, no mail delivery, no certificate issuance.

Nameserver service ​

The single field, Nameserver service, has two options.

PowerDNS ​

Runs DNS on this server. The option describes it as offering very high performance, instant start-up, and low memory requirements.

Choosing it installs, configures, and enables PowerDNS on this server. This is the option to pick when you want the panel to manage zones for the domains it hosts.

Disabled ​

Runs no DNS server here. Pick this when DNS is handled elsewhere, for example at a registrar or an external provider. AdminBolt then serves no zones locally, and the records shown for a domain are not authoritative for it.

Save Settings applies the choice. Changing it starts or stops DNS on the server, so expect DNS-related services to restart.

Warning: Switching to Disabled on a server that currently answers for hosted domains takes those domains offline unless another nameserver is already authoritative for them and the delegation points there.
