Quick Start Guide for Domain Name
Service (DNS)
This quick start guide assumes that you have already done two things:
1. You have registered your domain with InterNIC or some other
registration service. If you have not, refer to the FAQ section on
Cobalt’s web site (http://www.cobalt.com/support, under the
Knowledge Base link) for information on registering your domain
name.
For more information on registering a Web site, visit the Internet
Corporation for Assigned Names and Numbers (ICANN) at
http://www.icann.org.
2. You have created the Web site on the RaQ 3. For instructions on
how to do this, see “Adding a virtual site” on page 43.
In the following examples, we will configure a sample domain called
“mydomain.com” for Web service and e-mail service using a sample
IP address 192.168.10.10.
IMPORTANT: Substitute your domain name and IP address where the
sample domain name or sample IP address appears.
The recommended minimum configuration for Web and e-mail service
requires these records:
• An Address (A) Record for mydomain.com which points to
192.168.10.10
• An Address (A) Record for www.mydomain.com which points to
192.168.10.10
• A Mail Server (MX) Record for mydomain.com which points to
www.mydomain.com
• A Reverse Address (PTR) record for 192.168.10.10 which points to
mydomain.com
