Description

In DhcpPktHandler.java - this is how the destination ip address is set for server replies:

ip4Reply.setDestinationAddress(DhcpMConstants.BCAST_IP);

not according to rfc 2131:
If the broadcast bit is not set and 'giaddr' is zero and 'ciaddr' is zero, then the server unicasts DHCPOFFER and DHCPACK messages to the client's hardware address and 'yiaddr' address.
