Forgive the perhaps stupid question. I hope I can make it understandable. I am a complete beginner and so far couldn't find clear information on this.
I have different domains on a name server and manage different websites with aaPanel on my own VPS under one and the same IP. All Record A entries on the name server point to this IP.
How and at what point does the Internet recognize that there are different websites behind this IP? What do I have to do and what do I have to pay attention to to ensure this?
