A number of application-layer protocols make use of IP broadcasts or multicast messages for functions such as local service discovery or name resolution. Some of these functions can only be implemented efficiently using such mechanisms. When using broadcasts or multicast messages, a passive observer in the same broadcast domain can trivially record these messages and analyze their content. Therefore, broadcast/multicast protocol designers need to take special care when designing their protocols.
