DNS Server

The Antcas server has a built-in DNS server. This makes it possible to route names. The configuration is done in the Infrastructure under the Server, Network, DNS Server.

The server is only available once a configuration has been created. All changes are applied immediately.

Note: For an internal name to be resolved by the server itself, the DNS server may need to be set to 127.0.0.1 in the IP settings. And the current DNS server must be entered in the DNS forwarding.

Forwarding

If the requested name is not found on the DNS server, further DNS servers are queried in sequence.

Here you can enter the IP of the router, that of the Internet provider or the public DNS servers.

Note: Some Internet providers or routers use a DNS filter to protect against unsafe websites. Therefore, ask your customer if such a service is used and then only enter the DNS addresses being used.

Google

8.8.8.8
8.8.4.4

Cloudflare

1.1.1.1
1.0.0.1

Quad9

9.9.9.9
149.112.112.112

The addresses of the forwarding can be sorted. The query sequence is from top to bottom.

Reverse Zones

The reverse zones are automatically generated. Nevertheless, it is possible to set them up separately. For this purpose, zones with the suffix .in-addr.arpa are used.

Example Configuration

In this example, a zone named demo.my.antcas.com was created and an A-record was entered. It is only necessary to delete the semicolon and change the IP address 127.0.0.1.
