Hiera returns whatever it reads from your data file. If your json
deserialized to an array, that is what Hiera will return to you.

You might want to hand the whole respective data structure into your
define (all code untested):
$nic_list = keys($nics)
network_config { $nic_list: data => $nics }
define network_config($data) {
$ip = $data[$name]["ip"]
...
[ your implementation here ]
}
Depending on where else you need this specific data, you may
alternatively tailor it in a way that will enable you to just
create_resources("network_config", $nics)
As an aside, this design looks rather cumbersome and limiting you. I
found that hiera is most powerful and intuitive if it can itself figure
out which dataset to return (e.g. <hostname>.json) and splitting things
out into many keys.
Of course, it's not a one-size-fits-all issue, if your mileage is better
this way, feel free to stick to it, of course.
