Possibility to use zero-ui https without domain name

[squromiv]

I am newbie to Zerotier and network technologies. I rented VPS with static IP address. Used dockerized ztncui-aio controller. It workes well. Devices are connected.

And now I want to try zero-ui. Following the description, it can work with HTTPS using domain name. If I have no possibility to buy domain name, can I use somehow this feature with IP address of VPS?

Use free ddns services like https://www.duckdns.org/

Thanks! I managed to launch zero-ui by this method.
