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

Encryption protects confidential information against unauthorised access. With an

encryption system, data packets can be sent securely over a network. The Gigaset

SX763 WLAN dsl offers WEP encryption and WPA for secure data transfer over wireless

networks.

Ethernet

Ethernet is a network technology for local networks (LANs) defined by the IEEE as stand-

ard IEEE 802.3. Ethernet uses a base-band cable with a transfer rate of 10 or 100 Mbps.

Static IP address

A static IP address is assigned to a network component manually during network con-

figuration. Unlike the Dynamic IP address, a static (fixed) IP address never changes.

Firewall

Firewalls are used by network operators as protection against unauthorised external

access. This involves a whole bundle of hardware and software actions and technologies

that monitor and control the data flow between the private network to be protected and

an unprotected network such as the Internet.
