Gigaset Router / de / A31008-E105-B100-2-19 / glossary.fm / 05.06.2003

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 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 Router has a

Private IP address

and a

Public IP address

.

IP address pool
The Gigaset Router'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 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

implementing Virtual Private Networks (

VPN

). It covers most of the features of PPTP but

with less overhead and is better for managed networks.
LAN
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 local network can be connected to other local networks

or 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 802.11b

-standard network.

Lease time
Lease Time defines the period of time in which the PCs retain the

Dynamic IP address

assigned to them by the

DHCP

server without changing them.

Local IP address

Private IP address

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.
Mbps
