Aliases domains to master site with wordpress multisite installation not correctly redirect

Hi,

For example I have master-site.tv that have the wordpress multisite installation.

Also, I have alias-site.net.

In master-site.tv cPanel I have created the Alias alias-site.net.

After I have change the A value in DNS about alias-site.net with the master-site.tv A value.

Now if I write the alias-site.net url in browser I have this, and it is not what I axpected:

URL: http://master-site.tv/wp-signup.php?new=alias-site.net

and the message is "The site you were looking for, http://alias-sitenet.master-site.tv/, does not exist."

What I expected is that the content and subsite about *.alias-site.net/* are equal same as *.master-site.tv/*

What is wrong in my settings?
