You don't understand how $report_data{$domain}{$provider} is a reference?
If not, if you were to define things all at once it would be like this:
my %report_data = (
$domain => {
$provider => {
'error' => '0',
... # other stuff here
}
}
}
The reason it's a reference is because you have a scalar value (hash value $report_data{$domain}) pointing to a hash reference.
From perldoc -f perldata:
...
All data in Perl is a scalar, an array of scalars, or a hash of scalars
...
Although a scalar may not directly hold multiple values, it may contain a reference to an array or hash which in turn contains multiple values.
...
A hash isn't a scalar, it's a hash, but a reference is a scalar, so it can hold that in the value of the hash where the key is $provider.

It's sad that a family can be torn apart by such a such a simple thing as a pack of wild dogs
