Technical Summary

   A number of application-layer protocols make use of IP broadcasts or
   multicast messages for functions like local service discovery or name
   resolution. When using broadcasts or multicast messages, a passive 
   observer in the same broadcast/multicast domain can trivially record 
   these messages and analyze their content.  This document highlights 
   potential privacy issues that occur when protocol designers make 
   use of broadcast / multicast messages to exchange information that 
   can expose individuals to privacy threats. 

Working Group Summary

The document was discussed at length in the WG, following some experiments that 
were made over the IETF network. Because of the obviousness of the issues and 
usefulness of the document, there was little real discussion about the 
intention the document. There were comments for completeness from C. Huitema, 
T. Chown, T. Hebert, J. Touch, and the document shepherd, and these were all 
addressed.

Document Quality

The document is based on protocol behavior observed during experiments on 
operational networks (including the IETF meeting network)

Personnel

The document shepherd is Juan Carlos Zuniga. The responsible Area Director is 
Suresh Krishnan.
