Appendix: Glossary
Default Gateway (Access point): Every non-access point 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.Broadbandaccess point.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 "Broadbandaccess point.com" into your Internet browser), the user will be 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: 192.168.1.2. 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. In which 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 is followed by consecutive trailing 0's, such as
