Flight Radar Server

[CavemanC224]

Looks like a server for on a local computer so how do you make it accessible from the internet with dynamic ip ?
Using "always up" or an alternative way ?

Sorry, forget to answer this question.

I use a domain provider, which registers my domain. The current IP transfers my router to the provider. The routing of the different subdomains happens via DNS, whose entries I can manage yourself.

What happens in my LAN, I do with different servers and different services (e.g., firewall, web server, etc.)
