how to disable direct access to a web site by ip address

nginx dns ip server cloudflare

server {    listen      80 default_server;    listen      [::]:80 default_server;    server_name "";    return      444;}

You need to specify default_server parameter so that all non available server requests goes to this server block which throws 444 error.

You can use redirect, nginx config:

server {        listen 80;        server_name IP_ADDRESS;        return 301 http://YOUR.DOMAIN;}

You can just add a server directive before others.

server {    listen 80;    server_name _;    return 404;}
