3.4.3.8.2 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.
