Dynamic Domain Name Service (DDNS) is a service used to map a domain name to the dynamic IP
address of a network device. QNAP NAS supports DDNS for quick system access on the Internet by an
easy-to-remember domain name (URL) instead of a lengthy IP address. Once the IP is changed, the
NAS will automatically update the information to the DDNS provider to ensure it is always available for
remote access.

1B: Enable the DDNS service and enter the DDNS account information on the NAS.
1C: The NAS will update the WAN IP information to the DDNS provider automatically.
2A: Connect to the NAS by the registered host name.
2B: The DDNS provider will map the WAN IP updated by the NAS to the host name should the IP
change.
