For the Domain Name Server (DNS) Address setting, select one of the following radio 

buttons:

Get Automatically from ISP. Your ISP uses DHCP to assign your DNS servers. Your 
ISP automatically assigns this address. 

Use These DNS Servers. If you know that your ISP requires specific servers, select 
this option. Enter the IP address of your ISP’s primary DNS server. If a secondary 
DNS server address is available, enter it also. 

Click the Apply button.

Your settings are saved.

If you get address not found errors when you go to a website, it is 
likely that your DNS servers are not set up correctly. Contact your ISP 
to get the DNS server addresses.
