How to prevent a site from opening by IP?

Question

Network administration

Hello, I have a website on a specific domain. The domain hangs on the IP address (ns). The problem is that you can access the site by driving this IP into the browser. Google recently indexed this IP by accident and believes that the domain and this IP are duplicates, which actually affected the indexing.
How can I block access to a site by its IP? The first thing that came to my mind was to redirect to .htaccess, but there are probably better ways.

If it helps: hosting firstvds.ru, freebsd, is managed by ISPmanager.

Thank you.

Answer 1

And an even more correct way is to configure the Apache virtualhost so that it responds only from the desired hostname (it costs * instead of the domain, probably). Or make a 301 Moved Permanently redirect in .htaccess, since it is already indexed.

Answer 2

.htaccess is the correct way.

Answer 3

In the ISP manager panel, enter the IP address management and for the desired IP, assign another domain as the default domain.

Answer 4

301 redirect to htaccess
RewriteCond %{HTTP_HOST} ^ip address$ [NC]
RewriteRule ^(.*)$ domain/ $1 [R=301,L]

Answer 5

htaccess or nginx rules
