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 service provider or system administrator for the correct primary or
secondary DNS IP numbers.
Many systems do not require that you enter a DNS number. If you are not sure,
leave the DNS field blank.
To enter a primary and secondary DNS number:
Tap the Query DNS check box to deselect it.
1.
Tap the space to the left of the first period in the Primary DNS field, and then
2.
enter the first section of the IP address.
Each section must be a number from 0 to 255.
Repeat step 2 for the second, third, and last sections of the Primary DNS field.
3.
Repeat steps 2 and 3 for the secondary DNS number.

IP address
Everyone who logs in to the Internet needs to have a unique identifier (an IP
address), whether permanent or temporary. Some networks dynamically assign a
temporary IP address when clients log in. The IP Address field lets you identify
whether your network provides automatic (dynamic) temporary IP addressing.
If your IP address is permanently assigned, you need to get that information from
your system administrator. If you are not sure, select Automatic.
