Redirect multiple sub domains query

[Mick Young]

Good day to you all,

I recently bought a domain lets say for eg fo###-#####.com it has a large amount of subdomains around 350,

I wanted to re-direct all the subs to the root domain, I have had a look at the .htaccess of the /public.html folder and it contains this.

Could one of you clever people tell me what this below means in terms of redirecting and if it is redirecting does it transfer the sub domains authority to the root domain?

Thank you in advance.

Hi @Mick Young

This portion:

# BEGIN WordPress
<IfModule mod_rewrite.c>
RewriteEngine On
RewriteBase /
RewriteCond %{REQUEST_URI} !^/[0-9]+\..+\.cpaneldcv$
RewriteCond %{REQUEST_URI} !^/\.well-known/pki-validation/[A-F0-9]{32}\.txt(?:\ Comodo\ DCV)?$
RewriteRule ^index\.php$ - [L]
RewriteCond %{REQUEST_FILENAME} !-f
RewriteCond %{REQUEST_FILENAME} !-d
RewriteCond %{REQUEST_URI} !^/[0-9]+\..+\.cpaneldcv$
RewriteCond %{REQUEST_URI} !^/\.well-known/pki-validation/[A-F0-9]{32}\.txt(?:\ Comodo\ DCV)?$
RewriteRule . /index.php [L]
</IfModule>

# END WordPress

Is the wordpress redirect which mostly handles how your permalinks are displayed

For this portion

RewriteCond %{HTTP_HOST} ^\*\.fo###\-####\.com$ [OR]
RewriteCond %{HTTP_HOST} ^www\.\*\.fo###\-#####\.com$
RewriteCond %{REQUEST_URI} !^/[0-9]+\..+\.cpaneldcv$
RewriteCond %{REQUEST_URI} !^/\.well-known/pki-validation/[A-F0-9]{32}\.txt(?:\ Comodo\ DCV)?$
RewriteRule ^/?$ "http\:\/\/www\.fo###\-#####\.com" [R=301,L]

These two lines handle an exception for AutoSSL

RewriteCond %{REQUEST_URI} !^/[0-9]+\..+\.cpaneldcv$
RewriteCond %{REQUEST_URI} !^/\.well-known/pki-validation/[A-F0-9]{32}\.txt(?:\ Comodo\ DCV)?$

So for this purpose they're unimportant.

It looks like this portion here redirects *.domain.tld and www.*.domain.tld is redirected to www.domain.tld

RewriteCond %{HTTP_HOST} ^\*\.fo###\-####\.com$ [OR]
RewriteCond %{HTTP_HOST} ^www\.\*\.fo###\-#####\.com$
RewriteRule ^/?$ "http\:\/\/www\.fo###\-#####\.com" [R=301,L]
