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.
Domain Name
