Title: How to Configuring DDNS on Ruijie Cloud？
I. Overview
When the Dynamic Domain Name System (DDNS) service is enabled, external users can access the device's resources using a fixed domain name, without needing to look up the WAN interface IP address. The device supports three DDNS protocols: Ruijie DDNS, No-IP DNS, and DynDNS.
II. Application Scenarios
1. When the egress line uses a dial-up connection with a dynamic IP address, binding the dialer interface to the registered domain name allows the domain name to be associated with the IP address for Internet access.
2. Once DDNS is successfully configured, you can access a server or device with a dynamic IP address using the domain name, without needing to manually update the IP address.
III. Configuration Notes
Before using the DDNS service, you must register an account and domain name with a third-party DDNS provider.
IV. Configuration Interface
(1) Click Project in the top menu bar of Ruijie Cloud.
(2) Click the target project on the project page.
(3) Click Device Config in the left pane.
(4) In the displayed dialog box, click Dynamic DNS in the Gateway column.

V. Configuration Procedure
Ruijie DDNS
Ruijie DDNS is a domain name service provided by Ruijie Cloud that automatically maps a device’s domain name to its IP address. Ruijie devices can communicate with each other through this service. Ruijie devices can communicate with each other through Ruijie DDNS.
Choose Project > Configuration > Devices > Gateway > Dynamic DNS > Ruijie DDNS.

(1) Toggle on DDNS Enable.
(2) Set the required configuration parameters.

Parameter	Description
Domain Name	Domain name bound to the service interface IP address.
Map to	IP address, to which the domain name is mapped. The options includePublic IP and WAN IP.
WAN Interface	One domain name can be mapped to only one IP address. Therefore, you need to specify the WAN interface bound to the domain name when multiple WAN interfaces are available. By default, the service interface is a WAN interface.
IP Address	The IP address to which the domain name is mapped. The IP address is fixed to 192.168.0.1.

(3) Read and select I have read and agreed to the User Agreement.
(4) Click Save.
No IP
Select the DDNS server with the domain name of [www.noip.com](http://www.noip.com/).
Choose Project > Configuration > Devices> Gateway > Dynamic DNS > No-IP.

(1) Set the required configuration parameters.

Parameter	Description
Service Interface	One domain name can be mapped to only one IP address. Therefore, you need to specify the WAN interface bound to the domain name when multiple WAN interfaces are available. By default, the service interface is a WAN interface.
Username & Password	Enter the username and password of the account registered with the DDNS service provider’s official website. Make sure to register in advance.
Domain	The domain name bound to the IP address of the service interface. One account can bind multiple domain names, but you can choose to bind only one domain name to the current service interface’s IP address. Only the selected domain name will be resolved to the WAN interface’s IP address.
IPv6	IPv6 DDNS service.

(2) Click Save.
DynDNS
Select the DDNS server with the domain name www.dyndns.org.
Choose Project > Configuration > Devices > Gateway > Dynamic DNS > DynDNS.
(1) Set the required configuration parameters.

Parameter	Description
Service Provider	The service provider.
Service Interface	One domain name can be mapped to only one IP address. Therefore, you need to specify the WAN interface bound to the domain name when multiple WAN interfaces are available. By default, the service interface is a WAN interface.
Username & Password	Enter the username and password of the account registered with the DNS service provider’s official website. Make sure to register in advance.
Domain	The domain name bound to the IP address of the service interface. One account can bind multiple domain names, but you can choose to bind only one domain name to the current service interface’s IP address. Only the selected domain name will be resolved to the WAN interface’s IP address.

(2) Click Save.
Verifying the configuration.
If Connection Status is displayed as Connected, the server connection has been successfully established. After completing the configuration, ping the domain name from the Internet. If the ping is successful, the domain name will be resolved to the WAN port’s IP address.
