Don't bother with the dns updater. Use a reverse connecting trojan. The server runs on your carputer. The client runs on some other machine. When your car connects to the internet, it will automatically connect to the client. It will give you the ip, as well as full control of your carputer. So if you have a GPS, you'll be able to connect and find out where your car is. If you have a reverse cam, you should be able to pick some details up,street signs or something. You can even listen to a microphone if you have one installed. Trojans nowdays are called RAT's (remote assistance tools) Remember, these things can be used for lagitamate purposes too. If anyone wants to play with these, let me know and I can provide links to forums, software, and I will be more than happy to pass on my knowledge. Youll still need to use no-ip but it will be on your home computer not your carputer. So since it doesnt have to update anything when it's suddenly in range, it will connnect to your home much quicker than having to update its own ip.
