Default Gateway (Router):
Every non-router IP device needs a default
gateway. When the device sends out an IP packet, if the destination is not in
the same network, the device will send the packet to default gateway, which
will then forward it to the destination.
DHCP:
Dynamic Host Configuration Protocol. This protocol automatically
assigns an IP address for every computer in your network.
DNS Server IP Address:
DNS stands for Domain Name System, which allows
Internet servers to have a domain name (such as www.Broadbandrouter.com)
and one or more IP addresses (such as 192.34.45.8). A DNS server will
maintain a database of domain names and respective IP addresses, so when
a domain name is requested (like typing “Broadbandrouter.com” in your
Internet browser), the user will get the corresponding IP address. The DNS
server IP address used by the computers on your home network is the location
of the DNS server your ISP has assigned to you.
DSL Modem:
DSL stands for Digital Subscriber Line. A DSL modem uses
your existing phone lines to transmit data at high speeds.
Ethernet:
A kind of standard of computer networks. Ethernet networks are
connected by special cables and hubs, and transfers data at up to 10/100
million bits per second (Mbps).
Idle Timeout:
Idle timeout is designed so that after no traffic has been
transferred to the Internet for a pre-configured amount of time, the connection
will be disconnected automatically.
IP Address and Network (Subnet) Mask:
IP stands for Internet Protocol. An
IP address consists four sets of numbers separated by periods, which
identifies a single, unique Internet computer host in an IP network. Example:
192.168.2.1. It consists of 2 portions: the IP network address, and the host
identifier.
The IP address is a 32-bit binary pattern, which can be represented as four
cascaded decimal numbers separated by “.”: aaa.aaa.aaa.aaa, where each
“aaa” can be anything from 000 to 255, or as four cascaded binary numbers
separated by “.”: bbbbbbbb.bbbbbbbb.bbbbbbbb.bbbbbbbb, where each “b”
can either be 0 or 1.
A network mask is also a 32-bit binary pattern, and consists of consecutive
leading
1’s followed by consecutive trailing 0’s, such as
