Broadcast
A broadcast is a data packet not directed to a particular recipient but to all the network 
components in the network. The Gigaset SX763 WLAN dsl does not pass on broadcast 
packets; they always remain within the local network (

) it administers. 

BSSID
Basic Service Set ID
BSSID permits unique differentiation of one wireless network (

) from another. In 

, the BSSID is the 

 of the 

. In wireless net-

works in 

, the BSSID is the MAC address of any one of the participants.

Client
A client is an application that requests a service from a 

server

. For example, an HTTP cli-

ent on a PC in a local network requests data, i.e. Web pages from an HTTP server on the 

. Frequently the network component (e.g. the PC) on which the client applica-

tion is running is also called a client.

DHCP
Dynamic Host Configuration Protocol
DHCP handles the automatic assignment of 

to network components. It was 

developed because of the complexity involved in defining IP addresses in large networks 
– especially the 

 – as participants frequently move, drop out or new ones join. 

A DHCP server automatically assigns the connected network components (DHCP 

 from a defined 

 thus saving a great deal of con-

figuration work. In addition, the address blocks can be used more effectively: Since not 
all participants are on the network at the same time, the same IP address can be 
assigned to different network components in succession as and when required.
The Gigaset SX763 WLAN dsl includes a DHCP server and uses it to assign automatic IP 
addresses to PCs in the local network. You can specify that the IP addresses for certain 
PCs are never changed.

DMZ
Demilitarised Zone
DMZ describes a part of a network that is outside the 

. A DMZ is set up, as it 

were, between a network you want to protect (e.g. a 

) and a non-secure network 

(e.g. the 

). A DMZ is useful if you want to offer 

 services on the Internet 

that are not to be run from behind the firewall for security reasons or if Internet appli-
cations do not work properly behind a firewall. A DMZ permits unrestricted access from 
the Internet to only one or a few network components, while the other network com-
ponents remain secure behind the firewall.
