Glossary
IP address
The IP address is the unique network-wide address of a network component in a net-
work based on the
TCP/IP
protocol (e.g. in a local network (LAN) or on the Internet). The
IP address has four parts (decimal numbers) separated by periods (e.g. 192.168.2.1).
The IP address comprises the network number and the computer number. Depending
on the
Subnet mask
one, two or three parts form the network number, the remainder
the computer number. You can find out the IP address of your PC using the ipconfig
command.
IP addresses can be assigned manually (see
Static (fixed) IP
address) or automatically
(see
Dynamic IP
address).
On the Internet
Domain names
are normally used instead of the IP addresses.
DNS
is
used to assign Domain names to IP addresses.
The Gigaset SE505 dsl/cable has a
Private IP address
and a
Public IP
address.
IP Pool Range
The Gigaset SE505 dsl/cable's IP address pool defines a range of
IP addresses
that the
router's
DHCP Server
can use to assign
Dynamic IP
addresses.
IPSec
Internet Protocol Security
The term IPSec covers a number of
Protocols
used for the encrypted transmission of data
packets over the Internet. IPSec uses digital certificates for device authentication. IPSec
is offered by Internet Service Providers for implementing Virtual Private Networks (VPN).

L2TP
Layer Two Tunneling Protocol
L2TP is an extension of
PPTP
and is offered by
Internet Service Providers
for implement-
ing Virtual Private Networks (VPN). It covers most of the features of PPTP but with less
overhead and is better for managed networks.
LAN
Local Area Network
A local network links network components so that they can exchange data and share
resources. The physical range is restricted to a particular area (a site). As a rule the users
and operators are identical. A LAN can be connected to other LAN's or to a wide-area
network (WAN) such as the Internet.
With the Gigaset SE105 dsl/cable you can set up both a wired local
Ethernet
network and
a wireless
IEEE
802.11g-standard network.

MAC address
Media Access Control
The MAC address is used for the globally unique identification of a
Network
adapter. It
comprises six parts (hexadecimal numbers), e.g. 00-90-96-34-00-1A. The MAC address
is assigned by the network adapter manufacturer and cannot be changed.
