IGMP (Internet Group Management Protocol) Multicasting
The HBA provides support for IGMP multicasting, which allows hosts connected to a
network to be updated whenever an important change occurs in the network. A
multicast is simply a message that is sent simultaneously to a pre-defined group of
recipients. When joining a multicast group, all messages addressed to the group will
be received by the user, much like when an email message is sent to a mailing list.
Domain Routing
Domain routing is used in multi- local network configurations. Normally, to access a
device connected to one from another on the network, its IP address must be used.
Activating domain routing (by clicking in the appropriate check box) allows the user
to access the computer by name (as well as IP address).
