Protocol route messages based on the IP Address of the destination. The format of an IP address
is a 32-bit numeric address written as four numbers separated by periods. Each number can be
from zero to 255.
IPSec
Internet Protocol Security is a security standard for network transmission. It provides
authentication and packet encryption over the Internet.
ISP
Short for Internet Service Provider, a company that provides access to the Internet, usually for a
monthly fee. The ISP provides a software package, username, password and access phone
number allowing users to log on to the Internet, browse the World Wide Web and send and
receive e-mail.
Local Area Network (LAN)
A computer network that spans a relatively small area. Most LANs are confined to a single
building or group of buildings. However, one LAN can be connected to other LANs over any
distance via telephone lines and radio waves. A system of LANs connected in this way is called
a wide area network (WAN)
MAC Address
Short for Media Access Control Address and in a hardware address that uniquely identifies each
node of a network.
NAT
Short for Network Address Translation, a routing protocol that allows global IP Addresses to be
translated into multiple private IP Addresses for use on internal LAN networks. The explosion
in the use of the Internet has created a critical problem for the Internet Assigned Numbers
Authority (IANA) which is in charge of assigning IP Addresses to Internet users, ISPs etc.. NAT
is a technology that has been introduced to help maximize the utilization of assigned IAN and
global IP Addresses.
Network Protocol
Network protocols encapsulate and forward data packets from one interface to another.
PAP/CHAP ISP
Short for Password Authentication Protocol and Challenge Handshake Authentication Protocol.
Most ISPs use either one for user identification. If your ISP doesn’t support these two protocols,
contact your ISP for an authentication script.
PPP
Short for Point-to-Point Protocol, a communications protocol for transmitting information over
standard telephone lines between devices from different manufacturers.
PPPoE
Short for PPP over Ethernet, relying on two widely accepted standards, Ethernet and the
Point-to-Point Protocol. It’s a communications protocol for transmitting information between
devices from different manufacturers over an Ethernet.
PPTP
Short for Point to Point Tunneling Protocol, PPTP encapsulates the packet for transmission over
the Internet. It is similar to creating a private “tunnel” over a large public network and has
almost equal security to a private network without actually leasing a private line.
Protocol
An agreed format for transmitting, sending and receiving data between two devices.
