In basic terms your IP is controlled by your ISP. If your ISP does not offer fixed IPs then you will have to accept that your IP will change at some point in time (probably at the most inconvenient time if you have bad luck).

  who to manage it:
  
  1. To link your IP, you just need to click on the link button in the setup tab of the interface. You will have to repeat this operation anytime your IP changes if it is dynamic.
  
  2. You can also opt for our DDNS solution: Instead of manually linking your IP, you give us a hostname that points to your IP, and use a DDNS solution to keep it up to date.
  
  3. The third option is to call a URL from a script whenever your IP changes.

Most routers can use a dynamic DNS service that will update a hostname with your router's WAN IP address whenever it changes. If you set that up, then you can enter that dynamic DNS hostname into the Linked IP section of your NextDNS settings. NextDNS will regularly check that hostname and update the linked IP whenever it changes.
