assigns. 

Select User-Defined if you have the IP address of a DNS server. 
Enter the DNS server's IP address in the field to the right. If you 
chose User-Defined, but leave the IP address set to 0.0.0.0, User-

second choice to User-Defined, and enter the same IP address, 
the second User-Defined changes to None after you click Apply. 

Select None if you do not want to configure DNS servers. If you do 
not configure a DNS server, you must know the IP address of a 
computer in order to access it.
