Hardware updater from Nakra Microtek

A quick search shows that others have suggested it, though nobody has confirmed that it works.

I have contacted Nakra Microtek. Apparently they have their own DDNS server and the IPC200A only works with that. It sends update messages every 1 minute to their server.

This was their reply: If you getting blocked with DynDNS that's mean you have problems with IP Changed too many. You couldn't do anything with the DynDNS to change their policy. So, This is why you have to use our IPC200A. We have total solution for DDNS just like DynDNS. let me explain how. Firstly we have our own developed DDNS server for resolved host name and the IPC200A does only IP update to our server. Basically it send the IP information to the server every 1 minute. Our IPC200A is well know in my country for handling this kind of problems.
