There is a bug with reverse DNS lookup in
InetAddress.getByName(String) when presented with a IP address
rather than a host name. |
public static InetAddress getByName(String s) throws UnknownHostException
InetAddress.getByName(String)
when presented with a IP address
rather than a host name. It will always attempt reverse DNS lookup of the
IP address. Therefore if reverse DNS is NOT setup correctly, a
significant delay (4-5 seconds on Windows) will occur for each lookup and
resolution may fail with an UnknownHostException
.UnknownHostException
