Obtain DNS: A Domain Name System (DNS) contains a mapping table for mapping between Domain Names
and IP addresses. On the Internet, every host has a unique and user-friendly name (domain name) such as
www.helloworld.com as well as an IP address. An IP address is a 32-bit number in the form of xxx.xxx.xxx.xxx,
for example 10.0.0.2. You can think of an IP address as a telephone number for devices on the Internet, and the
DNS will allow you to find the telephone number for any particular domain name. As an IP Address is hard to
remember, the DNS converts the friendly name into its equivalent IP Address.
You can obtain a Domain Name System (DNS) IP address automatically if your ISP provides it when you logon.
