How to set up Free Dynamic DNS with NO-IP
Most of ISP (Internet Service Provider) in the world will assign dynamic IP address instead of static for its customer. Dynamic IP will change automatically from time to time or a router reset. Running IP camera in house or self-hosting TeamSpeak 3 server might need dedicated address for remote client to use. Let's say if your router reset while you are away due to common circumstances such as power trip, you can't connect to your hosted application thanks to changed IP address. To resolve this issue, you may want to set up DDNS (Dynamic Domain Name Server) which will automatically update changed IP address to configured domain name. We will be using free Dynamic DNS from NO-IP, which can be set up on your router or using Dynamic DNS Update Client (DUC) for Windows.
