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 towards 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.Broadbandrouter.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 "Broadbandrouter.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, 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.
ISP Gateway Address: (see ISP for definition). The ISP Gateway Address is an IP address for the Internet router
located at the ISP's office.
ISP: Internet Service Provider. An ISP is a business that provides connectivity to the Internet for individuals and
other businesses or organizations.
LAN: Local Area Network. A LAN is a group of computers and devices connected together in a relatively small area
(such as a house or an office). Your home network is considered a LAN.
MAC Address: MAC stands for Media Access Control. A MAC address is the hardware address of a device connected
to a network. The MAC address is a unique identifier for a device with an Ethernet interface. It is comprised of two
parts: 3 bytes of data that corresponds to the Manufacturer ID (unique for each manufacturer), plus 3 bytes that
are often used as the product‟s serial number.
NAT: Network Address Translation. This process allows all of the computers on your home network to use one IP
address. Using the broadband router‟s NAT capability, you can access the Internet from any computer on your
home network without having to purchase more IP addresses from your ISP.
