the most update information.

Cable/DSL
This field indicates the Internet connection status. Its value is
Connected , Disconnected or Connecting.

WAN IP
Connected to the Internet through Cable or ADSL modem, the ISP will
offer the home gateway a WAN IP address to communicate with other
hosts in the Internet.

Subnet Mask
This field indicates a

83H83H

mask

used to determine what

84H84H

subnet

the WAN

85H85H

IP

address

belongs to. An

86H86H

IP address

has two components, the network

address and the

87H87H

host

address. For example, consider the IP address

192.168.168.182 with subnet mask is 255.255.255.0, the first three
numbers (192.168.168) represent the Class C network address, and the
forth number (182) identifies a particular

88H88H

host on this network.


Gateway
“Gateway” is a

89H89H

node

on a

90H90H

network

that serves as an entrance to another

91H91H

network

. For the home gateway, The “Gateway” is the next device,

which routes the traffic to the Internet.

DNS
Domain Name System (or Service or Server) is an Internet service that
translates domain names into IP addresses. Because the domain names
are alphabetic, they are easier to remember. However, the Internet is
based on

92H92H

IP addresses

. Every time you use a domain name, a

93H93H

DNS

service must translate the name into the corresponding IP address. For
example, the domain name www.example.com might translate to
198.105.232.4. The DNS system has its own

94H94H

network

. If one

95H95H

DNS

server

doesn't know how to translate a particular domain name, it will ask

its upper stream server, and so on, until the correct IP address is returned
or timed-out.

Secondary DNS
This is the secondary DNS to use when the primary DNS does not work.
