Privacy Considerations for Protocols Relying on IP Broadcast or Multicast
RFC 8386

Received changes through RFC Editor sync (created alias RFC 8386, changed title to 'Privacy Considerations for Protocols Relying on IP Broadcast or Multicast', changed abstract to 'A number of application-layer protocols make use of IP broadcast 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 broadcast or multicast messages, a passive observer in the same broadcast or multicast domain can trivially record these messages and analyze their content.  Therefore, designers of protocols that make use of broadcast or multicast messages need to take special care when designing their protocols.', changed standardization level to Informational, changed state to RFC, added RFC published event at 2018-05-17, changed IESG state to RFC Published)
