htaccess redirect to another subdomain with the same domain-extension

I need to redirect all users who don't have an 'allowed' IP-address to another subdomain. The users should be redirected to the other subdomain with the same URL.

For example:

This part is now working with the following code in my .htaccess file:

RewriteCond %{REMOTE_ADDR} !^10\.0\.1\.1$
RewriteCond %{HTTP_HOST} ^dev\.example\.(.*)$ [NC]
RewriteRule ^ https://www.example.com%{REQUEST_URI} [L,R=301,NE]

Besides that the domain can have different domain-extensions like: .com .net .pl .se

That means if the user try to navigate to dev.example.se/contact_us.php and don't have an 'allowed' IP-address - then the user should be redirected to www.example.se/contact_us.php

I can't figure out how to make the second part working.

You can capture last of domain name from RewriteCond itself and use a back-reference later in RewriteRule like this:

RewriteEngine On

RewriteCond %{REMOTE_ADDR} !^10\.0\.1\.1$
RewriteCond %{HTTP_HOST} ^dev\.example\.(.+)$ [NC]
RewriteRule ^ https://www.example.%1%{REQUEST_URI} [L,R=301,NE]

Take note of capture group (.+) in RewriteCond that captured value after dev.example from host name. Then we use a back-reference of %1 later in RewriteRule that replaces same value.

Note that you may also use this rule where example is not repeated again:

RewriteCond %{REMOTE_ADDR} !^10\.0\.1\.1$
RewriteCond %{HTTP_HOST} ^dev\.(example\..+)$ [NC]
RewriteRule ^ https://www.%1%{REQUEST_URI} [L,R=301,NE]
