Dynamic DNS update settings
A Dynamic DNS (DDNS) service allows a user whose IP address is dynamically assigned to be 
located by a host or domain name. Before a DDNS service may be used, you must create an 
account with the DDNS service provider. The provider will give you account information such as 
username and password. You will use this account information to register your IP address and 
update it as it changes. 
A DDNS service provider typically supports the registration of only public IP addresses. When 
using such a service provider, if your Digi device has a private IP address (such as 192.168.x.x or 
10.x.x.x), your update requests will be rejected. 
The Digi device monitors the IP address it is assigned. It will typically update the DDNS service or 
server automatically, but only when its IP address has changed from the IP address it previously 
registered with that service. 
DDNS service providers may consider frequent updates to be an abuse of their service. In such a 
circumstance, the service provider may act by blocking updates from the abusive host for some 
period of time, or until the customer contacts the provider. Please observe the requirements of the 
DDNS service provider to ensure compliance with possible abuse guidelines. 
The Dynamic DNS Update Settings page includes both settings and status information.
