It depends on the server settings and the type of web server. Usually, if you specifically do nothing, and the site is only one on the server, it will open on the IP address. It is easy to make so that for unknown domains, and for queries without the

If we are talking about some kind of massive virtual hosting, then the usual practice is to do this, that is, limiting access to the IP server. No one wants to listen to complaints from a disgruntled client, the site of which, on the occasion that turned out to be the first in the list, opens when you enter some other domain in the address bar, which for any reason indicates the server’s IP. The owner of that other domain will also not be happy to develop events.
