During the mailslot search, Advantage clients also send out an UDP/IP multicast packet that contains the name of the file server specified for the connection. All Advantage Database Servers running on an UDP/IP-enabled machine will receive this multicast packet. Each Advantage Database Server that receives this packet will inspect the packet, comparing its file server name to the name in the packet. If the names match the Advantage Database Server will respond to the client with all of its IP and IPX addresses, which the client can then use to connect to the Advantage Database Server. The multicast requests are sent on multicast address 22.214.171.124 and port number 2989.
