Dyndns ip address not updating
"dyndns" will update a dynamic host, "custom" will update a My Dyn DNS Custom DNS host and "statdns" will update a static host. You need some way to find out what is the real IP is.
The default value is "dyndns" and you cannot use other options (statdns|custom) unless you donate and gain access to the more advanced features. The simplest way is to connect to a some web page, which runs a reverse lookup service which can show the connecting IP address. To find a service that is able to display your IP address, do a google search.
