AWS Lightsail - IPv4 Public DNS

Question

Recently I found out the public IPv4 Public DNS domain from my Worpress in AWS Lightsail instance is public and indexed by Google.

This is becoming a huge problem because is around 4,000 urls already indexed and my main domain is around 20,000 and will start to lose relevancy.

Any ideas how to hide this from public? Redirect from https://ec2-1-234-56-789.compute-1.amazonaws.com/ to main domain ou something that's solve this problem?

Answer

Hello.

Looking at the document below, it seems that if you return "X-Robots-Tag: noindex" in the response header, it will not be indexed.  
In other words, I thought it would be a good idea to add a process on the application side that would return "X-Robots-Tag: noindex" in the response header when accessed from a domain other than the domain.

Or, how about configuring the web server (Apache, etc.) to block access from users other than the domain?  
```

ServerName howtoabroad.com
    DocumentRoot /var/www/html

SSLEngine on
    SSLCertificateFile /path/to/your/certificate.crt
    SSLCertificateKeyFile /path/to/your/private.key
    SSLCertificateChainFile /path/to/your/chainfile.pem

RewriteEngine on
        RewriteCond %{HTTP_HOST} !^domain\.com$
        RewriteRule ^.*$ - [F,L]

```
