Android getting ipv6 address from hostname

问题

I'm trying to to get IPv6 addresses from a hostname on an Android device.

My device is Nexus 7 and 6.0.1 version.

Below is the API I used:

InetAddress[] inets = InetAddress.getAllByName("hostname.com");
InetAddress address = InetAddress.getByName("hostname.com");

Those two API calls work fine for IPv4, but do not work for IPv6.

It shows the below errors:

01-10 10:04:18.945: W/System.err(474): java.net.UnknownHostException: Unable to resolve host "106.bmc.com: No address associated with hostname

I also tried nslookup in Android terminal, and it works fine with IPv6:

Is there any way I can get an IPv6 address from a hostname using Android APIs?

UPDATE: I have used the dnsjava library to solve my problem.
