Configuring a primary DNS server
A primary DNS server maintains a list of name records and their associated
IP addresses. This list is made available to other DNS servers if your domain is
registered with your country-specific domain-naming organization. Your Internet
service provider (ISP) can help you register your Internet server.
To configure a primary DNS server for your RaQ 4:
1. On the Server Management screen, click Control Panel. The Service
Settings table appears.
2. Click the check boxto enable the Domain Name System (DNS) Server (if it
is not already turned on).
3. Click Save Changes.
4. Click Parameters next to the DNS service in the Service Settings table.
5. Select Address (A) from the Add... pull-down menu.
6. Enter the host name and domain name you want to serve (for example, www
and mydomain.com) and enter its IP address (for example, 192.168.1.1).
7. You can enable Automatic Reverse Lookup Generation for this IP address
and host name pair so that IP address/host name pairs can be resolved in both
directions. Reverse lookup (PTR) records that are generated automatically
assume the network mask of 255.255.255.0 (24 bits.)
