Hello

I want to:
to create a CNAME entry for www.mydomainname.com pointing to mybrandname.myorderbox.com.

I went in WHM of the server for mydomainname.com. There I went to edit DNS Zone and added www.mydomainname.com 14400 in CNAME mybrandname.myorderbox.com

as well as: mydomainname.com 14400 in CNAME mybrandname.myorderbox.com

But nothing changed. When I type mydomainname.com I see the empty folder not mybrandname.myorderbox.com.

Please advise me what to do. We are on a dedicated server and I want to add CNAME entry for www.mydomainname.com but it doesn't happen.
