In line with other IP stack implementations, the BSD

network stack has historically converted packets sent to

the INADDR_BROADCAST destination addresses

address according to the address configuration of the

primary network interface. For example if your network

interface is configured as 192.168.100.33/24 and you send

actually be sent with a destination IP address of

criticized for various reasons. The primary reason is

that it becomes impossible to send UDP packets to

255.255.255.255 once the primary network (broadcast)

reason, it is possible to disable this behavior with this
