Summary[edit source]

Dynamic DNS (DDNS or DynDNS) is a method of automatically updating a name server in the Domain Name System (DNS). This is most often utilized when the end user has a dynamic IP address and wants to bind it to a static hostname.

The device is compatible with many different third party DNS services that provide the possibility to create a custom hostname and bind it to an IP address. The DDNS service periodically updates the IP address information of the hostname, making sure that the device remains reachable via the same hostname even in cases when its IP address has changed.

This chapter is an overview of the Dynamic DNS section for RUTX12 devices.

Dynamic DNS Overview[edit source]

By default, an unconfigured DDNS instance will be present in the Dynamic DNS Overview page (the figure below is an example of this). You can create more DDNS instances by entering a name and clicking the "Add" button or you can edit the existing instance since it is not operational by default.

Editing a DDNS instance[edit source]

To configure a DDNS instance, click the "Edit" button located next to it.

The figure below is an example of the edit page of the default DDNS instance called "MyDDNS" (already present in the device by default) and the table below provides information on the configuration fields contained in that page:

For example, if your device has a Private IP (i.e., on its WAN interface, then you can send this exact IP to DDNS server by selecting Private.
Network network interface; Default: wan Specifies which interface's IP address should be bound to the hostname
Check Interval integer [5..600000]; Default: 10 Frequency at which the device will check whether it's IP address has changed.
