Summary[edit | 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 router 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 {{{name}}} devices.

The information in this page is updated in accordance with the [[Media:{{{fw_version}}}.bin|{{{fw_version}}}]] firmware version.

Dynamic DNS Overview[edit | 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 | 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 router by default) and the table below provides information on the configuration fields contained in that page:


field name value description
Enable yes | no; Default: no Turns the DDNS instance ON or OFF
Service third party DNS service (chosen from list*) | -- custom --; Default: dyn.com Third party DNS service provider
Lookup host host; Default: yourhost.example.com Fully qualified domain name (FQDN) of your defined host. This is required to verify what the hostname's current IP address at DNS is (using nslookup/host command)
Hostname host; Default: yourhost.example.com Hostname that will be linked with the router's IP address
Username string; Default: your_username User name required to login to the third party DNS service; used to periodically login to your DNS service account and make necessary updates.
Password string; Default: your_password Password required to login to the third party DNS service; used to periodically login to your DNS service account and make necessary updates.
IP address source Custom | Public | Private | Script; Default: Custom Defines the source to read the system's IPv4-Address from, that will be sent to the DNS provider. So if, for example, your RUT has a Private IP (i.e., on its WAN interface, then you can send this exact IP to DDNS server by selecting Private
Network LAN | WAN | WAN2 | WAN3 | PPP | PPP_USB; 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
Force interval integer [5..600000]; Default: 72 Frequency at which IP update requests are sent to the DNS provider
