3.4.3.7.2 DNS 
A Domain Name System (DNS) contains a mapping table for domain name and IP address. In the 
Internet, every host has a unique and friendly name such as 
www.yahoo.com
 and IP address. The IP 
address is so hard to remember that you may just enter the friendly name 
www.yahoo.com
 and then the 
DNS will convert it to its equivalent IP address. 
You can obtain Domain Name System (DNS) IP address automatically if ISP provides it when you logon. 
Or your ISP may provide you with an IP address of DNS. If this is the case, you must enter the DNS IP 
address.
