Need add an asterix. for all the domains?

Dear Sir,

For Multi domains, Multisite
All the domains or just main domain ,need to add * for subdomains?
Enable WordPress Multisite with Subdomains.
After editing on the wp-config.php file and the .htaccess file I added a wildcard DNS by adding a subdomain with just an asterix * and that allows WordPress to create the subdomains for multisite.

Login to cPanel Go to subdomains and add one with just an asterix.
All the domains or just main domain ,need to add * for subdomains?

Q2
I get a new IP address,I need go to godaddy
DNS Zone File,edit, points all the domains to new IP and add *,
or I should go to WHM cpanel do that.

Thanks!
