Summary

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}}}_WEBUI.bin|{{{fw_version}}}]] firmware version.

Dynamic DNS Overview

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 New configuration name and clicking the Add new button or you can edit the existing instance since it is not operational by default.

[[File:{{{file_dynamic_dns_overview}}}]]

Editing a DDNS instance

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:

[[File:{{{file_dynamic_dns_configuration}}}]]

field name	value	description
Enable	yes | no; Default: no	Turns the DDNS instance ON or OFF
Use HTTP Secure	yes | no; Default: no	Enables SSL data encryption
Use IPv6	yes | no; Default: no	Use IPv6 for this configuration
Status	string; Default: N/A	Data on the last status update of the DDNS instance. When status is shown as "N/A", it means that the router has not been able to establish a connection to the DNS service provider
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., 10.140.56.57) on its WAN interface, then you can send this exact IP to DDNS server by selecting Private
Network	LAN | Wired (WAN) | WiFi (WAN3) | Mobile (PPP) | ETH1V6 | WWAN0V6 | WLAN0V6  ; Default: Wired (WAN)	Specifies which interface's IP address should be bound to the hostname
IP renew interval	integer [5..600000]; Default: 10	Frequency at which the device will check whether it's IP address has changed
Force IP renew	integer [5..600000]; Default: 72	Frequency at which IP update requests are sent to the DNS provider
