@pikachu_sensei @vkc you can use a provider who offers dynamic DNS (ddns) and configure your router to regularly update it. You'll need to open a port in your firewall, and set up a port forwarding rule.

If you're using CloudFlare as your name server, you can run a tunnel which will let you mask your IP address behind theirs. They've got a container that works really well for docker compose stacks, DDoS protection, and there's no need to open a port on your router.
