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 (LAN) it administers.

BSSID

Basic Service Set ID

BSSID permits unique differentiation of one wireless network (WLAN) from another. In

Infrastructure mode, the BSSID is the MAC address of the Access point. In wireless net-

works in Ad-hoc mode, 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

Internet. 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 IP addresses to network components. It was

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

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

A DHCP server automatically assigns the connected network components (DHCP Cli-

ents) Dynamic IP addresses from a defined IP pool range 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 Firewall. A DMZ is set up, as it

were, between a network you want to protect (e.g. a LAN) and a non-secure network

(e.g. the Internet). A DMZ is useful if you want to offer Server 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.
