(7) DDNS
As part of the DNS system, the Dynamic Domain Name System (DDNS) service dynamically
updates the IP addresses of the host names and allocates fixed domain names for systems
connected with dynamic IP addresses. This way, the DDNS service ensures the user’s access to the
network using the same DNS name regardless of the changes in the IP address.
The Workhorse/Premier series provide a dynamic DNS to ensure URL access in a dynamic IP
environment.
Its built-in web server feature enables remotely monitoring images through the Internet anytime.
