Glossary

DHCP

Dynamic Host Configuration Protocol

Internet protocol that handles the automatic assignment of IP addresses to

Network subscribers. The protocol is made available in the network by a

server. A DHCP server can, for example, be a router.

The phone contains a DHCP client. A router that contains a DHCP server can

assign the IP addresses for the phone automatically from a defined address

block. The dynamic assignment means that several Network subscribers

can share one IP address, although they use it alternately and not simulta-

neously.

With some routers you can specify that the IP address for the phone is never

changed.

Displayed name

VoIP provider feature. You can specify any name that is to be shown to the

other party during a call instead of your phone number.

DMZ (Demilitarized 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 permits unre-

stricted access from the Internet to only one or a few network components,

while the other network components remain secure behind the firewall.

DNS

Domain Name System

Hierarchical system that permits the assignment of IP addresses to Domain

names that are easier to note. This assignment has to be managed by a local

DNS server in each (W)LAN. The local DNS server determines the IP address,

if necessary by inquiring about superordinate DNS servers and other local

DNS servers on the Internet.

You can specify the IP address of the primary/secondary DNS server.

See also: DynDNS.

Domain name

Name of one (of several) Web server(s) on the Internet (e.g.,

www.gigaset.com). The domain name is assigned to the relevant IP address

by DNS.

DSCP

Differentiated Service Code Point

See Quality of Service (QoS).

DSL

Digital Subscriber Line

Data transfer technology that allows Internet access with, for e.g., 1.5 Mbps

over a conventional telephone line. Preconditions: DSL modem and the

appropriate service offered by the Internet provider.
