The LAN is a separate network from the Wide Area Network (WAN). In the case of
the CGNV, the WAN refers to all computers and other devices available on the cable
connection.
By default, computers on the WAN cannot identify individual computers on the LAN;
they can see only the CGNV. The CGNV handles routing to and from individual
computers on the LAN.
4.1.2

LAN IP Addresses and Subnets

IP addresses on the LAN are controlled either by the CGNV's built-in DHCP server
(see
DHCP Status
on page 29), or by you (when you manually assign IP addresses
to your computers).
For more information about IP addresses and subnets in general, see
on page 28.
4.1.3

DNS and Domain Suffix

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. 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 CGNV allows you to define a Domain Suffix to the LAN. When you
enter the domain suffix into your browser, you can reach the CGNV no matter what IP
address it has on the LAN.
4.1.4

Debugging (Ping and Traceroute)

The CGNV 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.
