How to set up DDNS (Dyndns) of TP-Link cable modem routers（Blue UI）
Most ISPs (Internet service providers) assign a dynamic IP address to the router and you can use this IP address to access your router remotely. However, the IP address can change any time and you don’t know when it changes. In this case, you might need the DDNS (Dynamic Domain Name Server) feature on the router to allow you and your friends to access your router and local servers (FTP, HTTP, etc.) using domain name, in no need of checking and remembering the IP address.
Note: DDNS does not work if the ISP assigns a private WAN IP address (such as 192.168.1.x) to the router.
Follow the steps below.
