IP Sewerage (WordPress)

Question

When I run SEO Site Check on my site, I get:

IP Canonicalization Test: Your site’s IP address is not redirected to your site’s domain name. This can cause problems with duplicate content if the search engine indexes your site under its IP address and domain name.

I am running Apache and the tip is to add the following to my .htaccess file:

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

Using this test , I found that there are 2 IP addresses on my site, so I added two rules to the Rewrite Engine section. But the website still failed the test.

Am I doing it right? Here is my .htaccess file:

# BEGIN W3TC Browser Cache
<IfModule mod_deflate.c>
    <IfModule mod_headers.c>
        Header append Vary User-Agent env=!dont-vary
    </IfModule>

    <IfModule mod_mime.c>
        # DEFLATE by extension
        AddOutputFilter DEFLATE js css htm html xml
    </IfModule>
</IfModule>

    RewriteRule .* "/wp-content/cache/page_enhanced/%{HTTP_HOST}/%{REQUEST_URI}/_index%{ENV:W3TC_PREVIEW}.html%{ENV:W3TC_ENC}" [L]
</IfModule>

RewriteCond %{HTTP_HOST} ^104\.24\.123\.248
RewriteRule (.*) http://www.example.com/$1 [R=301,L]
</IfModule>
