how to use IP canonicalization on Apache

Requirements to setup IP Canonicalization on Apache web-server:

1) You must require a dedicated IP address.
2) Add a rewrite rule in .htaccess file.

RewriteEngine On
RewriteCond %{HTTP_HOST} ^xxx\.xxx\.xxx\.xxx [nc,or]
RewriteCond %{HTTP_HOST} ^example.\.com [nc]
RewriteRule (.*) http://www.example.com/$1 [R=301,L]


Second variant:

RewriteEngine on
RewriteCond %{HTTP_HOST} ^xxx\.xxx\.xxx\.xxx$
RewriteRule .* https://example.com [R,L]

Replace xxx\.xxx\.xxx\.xxx with your dedicated IP address and replace example.com with your actual domain name.
