Register DDNS for the Synology NAS

DDNS (Dynamic Domain Name Service) simplifies connecting to your Synology NAS over the Internet by
mapping a hostname to its IP address. For example, DDNS allows you to access your Synology NAS using a
domain name (e.g. www.john.synology.me), with no need to remember an IP address (e.g. 172.16.254.1).

The servers of the DDNS service provider are working normally.

The Synology NAS is able to connect to the Internet.

DDNS will only run in a network environment where there is no proxy server required.

You can only enter one hostname for each DDNS provider.
