Here's the instruction from Günter Scholtz on how to redirect IP address to domain name in Nginx and Apache.
Setting up a Default Route in Nginx
Method 1. Return a 301 redirect for requests made to IP.
server {
listen 80;
listen [::]:80;
server_name 192.168.1.80;
add_header X-Frame-Options "SAMEORIGIN";
return 301 https://www.example.com$request_uri;
}
Method 2. Return a 301 redirect which only no other rule matches. ('server_name _' means non-matches server name)
server {
listen 80 default_server;
listen [::]:80 default_server;
server_name _;
return 301 https://www.example.com$request_uri;
}
Setting up a Default Route in Apache
Method 1. Redirect IP requests to domain name by adding a rewrite rule that matches the IP.
RewriteEngine On
RewriteBase /
RewriteCond %{HTTP_HOST} ^192.168.1.80$
RewriteRule ^(.*)$ http://www.example.com/$1 [L,R=301]
Method 2. Redirect all other request (with no subdomains).
RewriteEngine on
RewriteCond %{SERVER_NAME} !=www.example.com
RewriteRule ^ https://www.example.com%{REQUEST_URI} [END,NE,R=301]
