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.
4. Repeat steps 2 and 3 for the Secondary DNS number.
5. Tap OK.
