3.1.3
A DNS server is a server software program that performs Domain Name Services
(DNS). This involves taking a full host name such as www.example.com or a
domain name such as example.com and returning the corresponding Internet
Protocol (IP) address such as 93.184.216.119.
3.1.4
A domain is a location on a network, for instance example.com. On the Internet,
domain names are mapped to the IP addresses to which they should refer by the
Domain Name System (DNS). This allows you to enter "www.example.com" into your
browser and reach the correct place on the Internet even if the IP address of the
website's server has changed.
Similarly, the CGNV2 allows you to define a Domain Suffix to the LAN. When you
enter the domain suffix into your browser, you can reach the CGNV2 no matter what
IP address it has on the LAN.
3.1.5
The maximum transmission unit (MTU) of a communications protocol of a layer is the
size (in bytes) of the largest protocol data unit that the layer can pass onwards.
3.1.6
The CGNV2 provides a couple of tools to allow you to perform network diagnostics on
the LAN:

Ping: this tool allows you to enter an IP address and see if a computer (or other
network device) responds with that address on the network. The name comes
from the pulse that submarine SONAR emits when scanning for underwater
objects, since the process is rather similar. You can use this tool to see if an IP
address is in use, or to discover if a device (whose IP address you know) is
working properly.

Traceroute: this tool allows you to see the route taken by data packets to get
from the CGNV2 to the destination you specify. You can use this tool to solve
routing problems, or identify firewalls that may be blocking your access to a
computer or service.
