Hi, Regarding z/VM LAN broadcast simulation ...
Broadcast packets are marked as such by the guest (the device drivers). The guest LAN acts as a hub and delivers a copy of the broadcast packet to the data connection of every virtual adapter (NIC) coupled to that LAN regardless of the destination IP Address or the subnet mask. Well... not every adapter... The adapter has to be initialized and enabled for receipt of inbound broadcast... but I believe the drivers for the QDIO adapter will enable broadcast by default. >From David Boyes: >Another thought on the subject of DHCP.

Each virtual adapter (NIC) is assigned a unique MACADDR value when it is defined. That value is unique within the z/VM host system where the NIC and the LAN are defined.
