Defining Primary and Secondary DNS
The Domain Naming System (DNS) is a mechanism in the Internet for
translating the names of host computers into IP addresses. When you
enter a DNS number (or IP address), you are identifying a specific
server that handles the translation services.
Each IP address has four sections, separated by periods. In the Details
dialog, you enter each section separately. Each section of an IP address
is made up of a number from 0 to 255; numbers are the only allowable
characters in this field.
Note: Ask your Internet Service Provider or System Administrator
for the correct Primary or Secondary DNS IP numbers.
Tip: Many systems do not require that you enter a DNS. If you are
not sure, leave the DNS field blank.
