How to set up DDNS (NO-IP) of TP-Link cable modem routers (new logo)

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 modem router.

Here takes Archer CR700 as demonstration:

To set up DDNS, please follow the instructions below:

1. Log into the web-based management interface of the cable modem router. If you don’t know how to do that, please refer to How to log into the web-based management interface of TP-Link cable modem routers (new logo)?

2. Go to Advanced > Network > Dynamic DNS. Select the DDNS Service (NO-IP).
