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 box,
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.
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.
To enter a primary and secondary DNS:
1. Tap the Query DNS check box to deselect it.
2. Tap the space to the left of the first period in the Primary DNS field, and then
enter the first section of the IP address.
NOTE Each section must be a number from 0 to 255.
3. Repeat step 2 for the second, third, and last sections of the Primary DNS field.
