DNS
Domain Name System
Hierarchical system that permits the assignment of IP addresses to domain names that
are easier to remember. 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 enquiring 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 (several) Web server(s) on the Internet (e.g., www.gigaset.com). The domain
name is assigned to the relevant IP address by DNS.

Dynamic IP Address
A dynamic IP address is assigned to a network component automatically via DHCP. The
dynamic IP address for a network component can change every time it registers or at cer-

DynDNS
Dynamic DNS
DNS is used to assign domain names and IP addresses. For dynamic IP addresses this ser-
vice is now enhanced with Dynamic DNS. This permits the use of a network component
with a dynamic IP address as a server on the Internet. DynDNS ensures that a service can
always be addressed on the Internet under the same domain name regardless of the cur-
rent IP address.
