Summary
In this chapter, I explained the concept of multicasting. Unlike unicast, which is a form of point-to-point communication, and broadcasting, where all computers on a network receive the transmission, multicasting is the process of sending IP packets to a group of systems. Multicasting is typically used in applications that support real-time audio and video conferencing.
In Windows 2000, Microsoft has added a new feature to the DHCP service that creates a MADCAP server. The MADCAP server can be used to dynamically allocate multicast addresses to systems on the network. In this chapter, I walked through the process MADCAP uses to determine which addresses to assign. I then explained how to install and configure the MADCAP server.
