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

server

. For example, an HTTP 

client 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 

application is running is also called a client.

Connect on demand
Connect on demand means that applications such as a Web browser, Messenger and E-
mail automatically open an 

 connection when they are launched. This can lead 

to high charges if you are not using a 

. This function can be deactivated at the 

Gigaset SE366 WLAN to save call charges.

DHCP
Dynamic Host Configuration Protocol
DHCP handles the automatic assignment of 

to network components. It was 

developed due to the fact that in large networks – especially the 

 – defining 

IP addresses is very complex 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 configuration work. In addition, it also allows address blocks to be used more 
effectively: Since not all participants are in 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 SE366 WLAN includes a DHCP server and can automatically assign 
IP addresses to PCs in the local network. You can specify that the IP addresses for certain 
PCs are never changed.

DMZ
Demilitarized Zone, see also 

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 

which, for security reasons, will not run behind the firewall, or if Internet applications 
do not function correctly behind a firewall. A DMZ permits unrestricted access from the 
Internet to only one or a few network components, while the other network compo-
nents remain secure behind the firewall.
