Android java.net.UnknownHostException: Host is unresolved (strategy question)

by

I have come across this behaviour while using HttpUrlConnection. I am using simple workaround – I execute the following code just before using any url.

    try {
      InetAddress i = InetAddress.getByName(URLName);
    } catch (UnknownHostException e1) {
      e1.printStackTrace();
    }
// ... actually using URLName

For the first time I obtain here UnknownHostException but next usages of the url are successful (DNS server returns proper IP address and I can connect to the server).
