You could use my DynScalar module (found on CPAN):
use DynScalar;
my $domain;
my %hash = (

Yup! With a little rework

Obviously I must not be able to explain what I am trying to

Nope,
No typo, this is exactly what I am trying to accomplish... I want the
hash to store the variable (and thus be able to reference that variable
and it's current value later on) and not the value of the variable. You
are correct in the fact that it does not
I don't see how that could possibly work, since you are declaring the value
of $hash{1} to be $domain, which has not been initialized. You are
declaring $hash{1} to be the VALUE of $domain. When you change $domain
later, this won't update your hash retroactively. Maybe this is just a typo
