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 Giga762SX
WLAN dsl offers WEP encryption and WPA for secure data transfer over wireless net-
works.
