register my domain to my license?

On the "my licenses" leaves my license number for payment, but where it leaves my domain "unregistered". As registration? 

Thank you

you have to come and register at Unity with your domain name and then you will be issued a license. Unless you purchased one then you still have to sign up for unity I believe, then go to your account then to my license there you will see it.

Also contact support/tech support and they can tell you as well
