5.3 Glossary
Default Gateway (Router): Every non-router IP device needs to configure a default gateway 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 to 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 on the Internet for a
pre-configured amount of time, the connection will automatically get disconnected.
