Dynamic DNS
Any service you provide on the Internet can be accessed by Domain names . Your router's
Public IP address is assigned to this domain name. If your Internet Service Provider for
your local network's WAN connection assigns the IP address dynamically, the IP address
of the router can change. The assignment to the domain name will no longer be valid
and your service will no longer be available.
In this case you must ensure that the assignment of the IP address to the domain name
is regularly updated. This is handled by the dynamic DNS service (
DynDNS ). You can use
the DynDNS service to assign your Gigaset SE551 WLAN dsl/cable an individual static
domain name on the Internet even if it does not have a static IP address.
There are various providers on the Internet offering free DynDNS service.
The Gigaset SE551 WLAN dsl/cable uses the DynDNS service from DynDNS.org
(http://www.DynDNS.org).If you use the service of this DynDNS provider, then your
service can be reached on the Internet as a subdomain of one of the DynDNS.org
domains.
