IP address

The 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 full stops (e.g. 192.168.1.1). 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 forms 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 SE551 WLAN dsl/cable has a Private IP address and a Public IP address.

IP pool range

The Gigaset SE551 WLAN 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.

Local 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 local network can be connected to other local networks or to a wide-area network (WAN) such as the Internet.

With the Gigaset SE551 WLAN dsl/cable you can set up a wired local Ethernet network and a wireless IEEE 802.11g standard network (WLAN).

Lease time

The lease time defines the period of time for which the PCs keep the Dynamic IP address assigned to them by the DHCP server without changing them.

The MAC address is used for the globally unique identification of a Network adapters. 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.
