import java.net.Inet6Address;
import java.net.InetAddress;
import java.net.UnknownHostException;
public class Authentication {
public static void main(String[] args) throws UnknownHostException {
boolean found = false;
InetAddress[] addrs = Inet6Address.getAllByName("www.juliasoft.com");
for (InetAddress addr: addrs) {
if (addr.getCanonicalHostName().equals("231.13.35.1")) // "Hostname in Condition (Java)" warning issued here
found = true;
else if ("112.34.5.103".equals(addr.getCanonicalHostName())) // "Hostname in Condition (Java)" warning issued here
found = true;
found |= addr.getCanonicalHostName().startsWith("131."); // "Hostname in Condition (Java)" warning issued here
}
if (found)
System.out.println("OK");
}
}
Check if the warning actually corresponds to a real security issue related to authentication and, if that is the case, use a more secure authentication procedure.
