How can the Listen directive in the httpd.conf file be modified to restrict access to Xampp?

To restrict access to Xampp using the Listen directive in the httpd.conf file, you can specify a specific IP address and port for Apache to listen on. By setting the Listen directive to only allow connections from a specific IP address, you can restrict access to Xampp to only those clients connecting from that IP address.
