Dynamic DNS configuration with MikroTik

Using Dynamic DNS with MikroTik routers allows businesses and home users to quickly and easily access their networks from anywhere in the world. Unfortunately, setting up a Dynamic DNS service on MikroTik routers can be complex. Still, once configured correctly, it provides fast and reliable access to internal systems without having to remember constantly changing IP addresses.

Pre-configuration requirements

Open the DNS zone which you want to connect with Dynamic URL. Find the A or AAAA record which you would like to be updated dynamically and click on the arrows on the row for this record. Afterwards, you have to Activate the Dynamic URL in the pop-up. Once you do it, you will see example scripts, used for record update. In this setup, you will need the first one, which looks like this:

https://ipv4.cloudns.net/api/dynamicURL/?q=your-string-here
or
https://ipv6.cloudns.net/api/dynamicURL/?q=your-string-here
