Appendix E: Domain Name System
256 Cobalt RaQ XTR User Manual
Sample setup of DNS service
This sample setup assumes that you have already done two things:
1. You have registered your domain name. For more information on registering
a domain name, 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 XTR. For instructions on how to
do this, see “Developing Web pages” on page 190 and “Directory structure”
on page 242.
In the following examples, we will configure a sample Web site called
“www.mydomain.com” for Web and email services using a sample IP address
192.168.10.10.
The recommended minimum configuration for Web and email services requires
these records:
• A Reverse Address (PTR) record for 192.168.10.10 which points to
www.mydomain.com
• A Forward Address (A) record for www.mydomain.com which resolves to
192.168.10.10 (this record can be automatically generated when creating the
Reverse Address (PTR) record)
• A Forward Address (A) record for mydomain.com which resolves to
192.168.10.10
• A Mail Server (MX) Record for mydomain.com which resolves to
www.mydomain.com
✍
Note: Cobalt recommends that you enable the Automatic DNS
Configuration feature on a virtual site to create the DNS records.
For more information, see “Automatic configuration of DNS
records” on page 127.

Important: Substitute your domain name and IP address where the
sample domain name or sample IP address appears.
