Most ISPs 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 from time to time and you don’t know when it changes. In this case, you might apply 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 a domain name without 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.

Note: TL-MR3420_V5 is used for demonstration in this article.

1. Visit http://tplinkwifi.net, and log in with the password you set for the router. For details, please refer to How do I log into the web-based Utility (Management Page) of TP-Link wireless router?

2. Go to Advanced > Network > Dynamic DNS.

3. Select the DDNS Service Provider: NO-IP or DynDNS. If you don’t have a DDNS account, you have to register first by clicking Go to register. Then enter the username, password and domain name of your account.

4. Click Log In and Save.

Tips: If you want to use a new DDNS account, please click Logout first, and then log in with a new account.
