How to redirect IP address request to the proper domain name using Nginx

For SEO purposes, it is good practice to redirect permanently traffic directed to the IP address of a particular website to be re-written to the actual domain name.

This is very easy to do using Nginx web server. Simply add this server configuration block.

In this example I am using IP address 123.234.123.234 to be 301 redirected to domain name yourdomainname.com.

# -----------------------------------------------------

server {
listen 80;
server_name 123.234.123.234;
return 301 $scheme://www.yourdomainname.com$request_uri;
}
