Method Detail

getByName

public static InetAddress getByName(String s)
                             throws UnknownHostException

Deprecated.

There is a bug with reverse DNS lookup in 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.

Throws:

UnknownHostException
