1. Open NGINX configuration

Open terminal and run the following command to open NGINX configuration. If your NGINX configuration file is located somewhere else, then please update the file path below as per your requirement.

$ sudo vi /etc/nginx/nginx.conf

2. Redirect IP to Domain URL

server {
    listen 80;
    return 301 $$request_uri;

In the above case, we create a separate server block that listens to port 80. Since our server_name is same as IP address, this NGINX server will listen to all requests sent to your website’s IP address. The last line redirects all requests received by this server block to your domain We return a 301 response code for permanent redirect.

3. Restart NGINX server

It is important to make sure that your website’s IP address automatically redirects to your domain. Otherwise, your website users will be able to view your website both via its IP address as well as domain name, which can be confusing.

It will also result in duplicate content penalty as search engines may consider your website to contain duplicate content. This is because search engines will see your domain and IP address as two separate entities with same content. Also, if there are some backlinks to your IP address, and some links to your domain they won’t be consolidated as far as SEO is concerned, and it can lower your website’s rankings in search engine.

Typically, the redirection of IP to domain is done in domain registrar by adding an A record for it and does not require you to make any changes in NGINX. However, if you don’t have access to your domain registrar’s settings then you can follow the above steps for it.
