alias name or IP Address of mail server. So the DNS Server should be searched via the Internet actually and
the DNS record should be accurate.
According to the International usage and enhance the reliability and security, the DNS system must point to 2
DNS Servers.
Example:
Suppose we would like to setup a DNS Server applied as below situation:
1 Register a domain name, planet.com.tw.
2 The IP Address of Primary DNS Server is 61.11.11.11, and the host name is main.planet.com.tw.
The IP Address of Secondary DNS Server is 211.22.22.22, and the host name is main.planet.com.tw.
3 Connect to the Internet via Leased line or ADSL (Fixed IP).
4 Address Resolution for the following servers:
www.planet.com.tw (192.168.1.100) Web Server
mail.planet.com.tw (192.168.1.101) E-Mail Server
At first, we have to register 2 leased line/ADSL line for fixed IP.
Suppose the IP range provided by the ISP is below,
61.11.11.11 ~ 61.11.11.15
211.22.22.22~ 211.22.22.26
Visit the Network Information Center in local (i.e., the origination in Taiwan and China is TWNIC (Taiwan
Network Information Center) and CNNIC (China Network Information Center) respectively) and register the
domain name.
The Primary DNS Server:
Host Name dns1.planet.com.tw
IP Address 6 1 .11 .11 .11
The Secondary DNS Server:
Host Name dns2.planet.com.tw
IP Address 211 .22 . 22 .2 2
NOTE: The domain name which is register to the local Network Information Center should map to Fixed IP
absolutely.
