question: public static boolean validateBindAddress ( String bindAddress ) { if ( bindAddress == null || bindAddress . length ( ) == 0 ) return true ; if ( InetAddressUtil . validateHost ( bindAddress ) == null ) return false ; return true ; }
target:  Validates the bind address. The address may be a host name or IP address, but it must not be empty and must be usable for creating an InetAddress. Cannot have a leading '/' (which InetAddress.toString() produces).
