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

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.
