DynDNS
Dynamic DNS
The assignment of Domain names and IP addresses is handled by the Domain Name
Service (DNS). This service is now enhanced with so-called Dynamic DNS (DynDNS) for
Dynamic IP addresses. This enables 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 current
IP address.

encryption system, data packets can be sent securely over a network. The Gigaset
SE361 WLAN offers WEP encryption and WPA encryption for secure data transmission
over wireless networks.

Firewall
Firewalls are used by network operators as protection against unauthorised external

that monitor and control the data flow between the private network to be protected and
an unprotected network such as the Internet.
