Chapter 18: 
Configuring DNS Settings
Network > DNS
The Domain Name System (DNS) is a distributed, hierarchical system that provides a method 
for identifying hosts on the Internet using alphanumeric names called fully qualified domain 
names (FQDNs) instead of using difficult to remember numeric IP addresses. 
The Network > DNS page allows you to manually configure your DNS settings, if necessary.
In the DNS Settings section, select Specify DNS Servers Manually and enter the IP 
address(es) into the DNS Server fields. Click Apply to save your changes.
