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 83H8 3H83Hmask used to determine what 84H84H84Hsubnet the WAN 85H85 H85HIP

address belongs to. An 86H86H86HIP address has two components, the network

address and the 87H87 H87Hhost 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 88H88 H88Hhost on this network.

Gateway

“Gateway” is a 89H89H89Hnode on a 90H90H90Hnetwork that serves as an entrance to another

91H9 1H91Hnetwork. 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 9 2H92H92HIP addresses. Every time you use a domain name, a 93H93H93HDNS

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 94H94 H94Hnetwork. If one 95H95H95HDNS

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

Domain name is a name, which identifies one or more IP addresses. This

field represents the domain name obtained from your ISP.
