PPPoE
Protocol used to connect to the Internet via ADSL or DSL.
Private IP address
The private IP address (local IP address) is the address of a network device on a
local network (LAN). The provider assigns this address at will. DSL routers have a
public IP address for the WAN and a private IP address for the LAN. The following
IP ranges are recommended for private IP addresses:
10.0.0.0…10.255.255.255
à
Class A.
172.16.0.0…172.31.255.255
à
Class B.
192.168.0.0…192.168.255.255
à
Class C.
The first IP address xxx.xxx.xxx.0 and the last IP address xxx.xxx.xxx.255 in a
network segment cannot be used, as xxx.xxx.xxx.0 is reserved for the network
and xxx.xxx.xxx.255 for broadcasting.
Protocol
A protocol describes the type of communication on a network. It contains rules on
opening, managing, and closing a connection, on data formats, time sequences,
and possible error correction. Different protocols are needed to allow two
applications at different levels to communicate with each other, e.g. TCP/IP
protocols on the Internet.
Provider
Provider of telecommunications services. Also referred to as network provider or
network operator.
Public IP address
The public IP address is the worldwide valid (global) address of a network device
on the Internet. The ISP assigns these addresses. A network device with public
IP address is a device establishing a connection between local network LAN and
the Internet.
DSL routers have a private IP address for the LAN and a public IP address for the
WAN (Internet).
RNDIS
Remote Network Driver Interface Specification. Protocol to generate a virtual
Ethernet when communicating between the device and a computer via USB.
Router
A router forwards data packages from a local network LAN to a higher network
while selecting the fastest route. A router allows for connecting different networks
with different network topologies. For example, the router connects a local network
to the Internet.
Secure Sockets Layer
See SSL.
Server
A server accepts requests from clients, processes them and responds to the
clients. Network servers, data servers, Web Servers also assume services for
other network devices.
Simple Mail Transfer
Protocol
See SMTP.
SMTP
The SMTP protocol is a TCP/IP protocol. It controls e-mail traffic on the Internet.
The ISP provides the SMTP server (mail server).
SSL
Outdated form for TLS; see TLS.
Standard gateway
A default gateway (see Default Gateway as well as DSL router) is also referred to
as a network address used by clients to send their packages if the target address
is outside the immediate network.
