We have just added a new option to the DynDNS Service plug-in
for Simple DNS Plus, which allows you to intercept dyndns.org (Dyn.com) updates.
Many Internet/NAT routers (and other devices) have a built-in function to update a dyndns service (a.k.a. "ddns") whenever the public IP address changes. This is often hard-coded to use a few specific dyndns providers / update formats, and dyndns.org (Dyn.com) is typically one of these.
With Simple DNS Plus (on a public static IP address), you can now run your own dyndns service and pretend to be dyndns.org (Dyn.com) - and have such routers update it.
The updated plug-in will also be included in the future builds of Simple DNS Plus (v. 6.0 build 119 and later).
The plug-in is released into the public domain as open source. You are most welcome to fork the source code, contribute code enhancements, and/or use the source code as a starting point for developing your own plug-ins.
