In an Android app executing the following piece of code to determine if a hostname is present in my network:

for (int i = 0; i < listOfHostnames.size(); i++) {
     //noinspection unused
     String hostname = listOfHostnames.get(i).getAddress();
     try {
      InetAddress test = InetAddress.getByName(listOfHostnames.get(i).getAddress());
      //noinspection unused
      String testHost1 = test.getHostAddress();
      Logging.logw("Found", testHost1);
     } catch (Exception e) {
      Logging.logw(e.getClass() + " InetAddress EX", e.getMessage());
      continue;
     }
     //.....
}

It works on most devices i tested, but it fails on a Samsung Galaxy Tab-A (SM-T550) with this following exception (hostname isn't that one):

W/class java.net.UnknownHostException InetAddress EX: Unable to resolve host "hostname-abc": No address associated with hostname

Do Samsungs need some extra code,or is there another way to check if a hostname is present on the network?

EDIT

listOfHostnames is a list of objects, where the getAddress method returns hostnames, such has "BrandT-12-28183" (the type of hostnames the devices using have)

I also have these permissions declared on the manifest:

<uses-permission android:name="android.permission.INTERNET" />
<uses-permission android:name="android.permission.ACCESS_NETWORK_STATE" />
