====== Dynamic DNS ====== DD-WRT NXT has presets for several Dynamic DNS providers: * dyndns.org * changeip.com * he.net * no-ip.com If your provider is not listed, you can also use "Custom Configuration" and a Custom update URL(most providers will provide those to users). For the Custom Update URL, you can inject the needed informations from the input fields as following: Example (pure fictional example URL): ''http://[USERNAME]:[PASSWORD]@testuser123.org/update.cgi?hostname=[DOMAIN]&myip=[IP]'' Where the following parts of the URL will be replaced during the request with the according fields: * [USERNAME] will be replaced with the value of the "Username" field * [PASSWORD] will be replaced with the value of the "Password" field * [DOMAIN] will be replaced with the value of the "Domain" field * [IP] will be replaced with Value, according to the "Check IP at" settings (described below) ==== Check IP at ==== The setting of this field will change which IP will be passed to your Dynamic DNS provider for Custom or other providers. * WAN - The WAN IP-Address of the router will be passed to the DNS Provder as your outbound IP (this may only be the case for DSL Modems) * Internet - The outbound IP-Address as for the checkip.dyndns.com API (works for DSL Modems as well as Routers) ==== Timeout Configuration ==== * Verify - The configured Domain will be verified to match the IP from "Check IP at" every **N** minutes * Refresh - The Update will be performed every **N** hours defined here ==== Example Configuration View ==== {{ :howto:use_cases:routing:dyndns.png?direct&600 |}}
