IP address

An IP address is the unique network-wide address of a network component in a network 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 implementing 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 Area 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.
