> Hive has code occurences as following:
> {code:java}
> InetAddress.getByName(String){code}
>  * Only returns {*}one IP address{*}, even if multiple (IPv4 and IPv6) exist.
>  * May return an IPv4 address even when an IPv6 address is preferred.
> Safer Alternative:
> Use InetAddress.getAllByName(hostname) to get all possible addresses and explicitly choose an IPv6 one if needed.
