GLOSSARY

Default Gateway (Router): Every non-router IP device needs to configure a
default gateway's IP address. When the device sends out an IP packet, if the
destination is not on the same network, the device has to send the packet to
its default gateway, which will then send it out toward the destination.
DHCP: Dynamic Host Configuration Protocol. This protocol automatically gives
every computer on your home network an IP address.
DNS Server IP Address: DNS stands for Domain Name System, which allows
Internet servers to have a domain name (such as www.intellinet-network.com)
and one or more IP addresses (such as 192.34.45.8). A DNS server keeps a
database of Internet servers and their respective domain names and IP
addresses so that when a domain name is requested (as in typing "intellinet-
network.com" into your Internet browser), the user is sent to the proper 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 standard for computer networks. Ethernet networks are connected
by special cables and hubs, and move data around at up to 10/100 million bits
per second (Mbps).
Idle Timeout: Idle Timeout is designed so that after there is no traffic to the
Internet for a pre-configured amount of time, the connection will automatically
be disconnected.
IP Address and Network (Subnet) Mask: IP stands for Internet Protocol. An IP
address consists of a series of four numbers separated by periods that
identifies a single, unique Internet computer host in an IP network.
Example:
192.168.2.1 consists of two parts: an IP network address and a 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 (subnet) mask is also a 32-bit binary pattern, and consists of
consecutive leading 1's followed by consecutive trailing 0's, such as
11111111.11111111.11111111.00000000. Therefore, sometimes a network
mask can also be described simply as "x" number of leading 1's. When both
are represented side by side in their binary forms, all bits in the IP address that
correspond to 1's in the network mask become part of the IP network address,
and the remaining bits correspond to the host ID.
Example:
If the IP address for a device is, in its binary form,
11011001.10110000.10010000.00000111, and if its network mask is
