[[network-general]] === General Network +The handling of the lowest address on an IPv4 (sub)net (host 0) has been changed so that packets are not sent as a broadcast unless this address has been set as the broadcast address. This makes the lowest address usable for a host. The old behavior can be restored with the `net.inet.ip.broadcast_lowest` sysctl.
