How do I reserve my Synology DDNS hostname?
Purpose
If you received an email notification about your DDNS hostname expiring soon, you will have to renew the hostname to continue using it. The Synology DDNS hostname for your Synology product will be automatically renewed daily and is reserved for your own use.1
This article provides information on how to reserve your DDNS hostname based on your internet connection status.
Resolution
Reserving on DSM
If you received a DDNS expiration notification email, your Synology device might not be able to detect a heartbeat, or the internet. Therefore, your DDNS hostname is not reserved. To make sure your Synology device can detect the internet, Heartbeat must be enabled.
Go to the DDNS page to enable the Heartbeat service.
DSM: Go to Control Panel > External Access > DDNS. Select your DDNS and click Edit, and tick Enable Heartbeat.
SRM: Go to Network Center > Internet > QuickConnect & DDNS > DDNS and select your DDNS. Click Edit > Heartbeat.
After the heartbeat has been enabled, DSM will automatically continue reserving the Hostname.
Reserving on Synology Account
Go to Synology Account to manually renew your Synology DDNS hostname:
- Sign in to your Synology Account.
- Go to the Devices page, find the registered Synology products and their Synology DDNS hostnames. If a Synology DDNS hostname is about to expire, you will find a renew icon.2
- Click Update to reserve the Synology DDNS hostname. The Synology DDNS hostname is valid for the next 60 days.
Notes:
- Synology DDNS hostnames will be made available to other users if they are not used for more than 60 days.
- The icon will not be shown if the DDNS has already expired. Set up your DDNS hostname again to continue using the same one.
