Using Dyn’s dynamic DNS eliminates the headache and human error associated with tracking ever-changing IP addresses and allows you to avoid the alternative of purchasing pricey static IPs. When your IP address changes, you need your hostname to be updated as quickly as possible.

If the IP address passed to the system is not properly formed, it will be ignored and the system’s best guess will be used.
When a change in IP address is found or a user alters any of their settings, the client should perform an update.
All updates are sent using a well-formed HTTP request.
An example would be: Actual HTTP request should look like following fragment.
