Working group issue tracking:

 The goal of the Zero Configuration Networking (ZEROCONF) Working
 Group is to enable networking in the absence of configuration and
 administration. Zero configuration networking is required for
 environments where administration is impractical or impossible,
 such as in the home or small office, embedded systems 'plugged
 together' as in an automobile, or to allow impromptu networks as
 between the devices of strangers on a train.

 ZEROCONF will make networking as easy as possible,
 but no easier. In some cases other considerations may dominate
 ease of use. For example, network security requires some
 configuration which may not be as easy as the unacceptable
 alternative of 'no security.'

 The working group was orginally chartered to
 develop a requirements specification for host and application
 operation in environments lacking configuration. The areas
 for consideration included:

 * Interface Configuration (IP address, network prefix,
 gateway router)

 * Name-to-Address Translation

 * Service Discovery

 * Automatic allocation of Multicast Addresses

 * Sufficient security features to prevent networks
 from being any less secure than networks which do not use
 ZEROCONF protocols

 The ZEROCONF WG could not come to a consensus regarding these
 requirements. A ZEROCONF requirements document will not be
 published by this working group.

 This WG will produce one protocol specification, describing
 automatic generation and assignment of link-local IPv4 addresses
 in environments lacking host configuration (static or using DHCP).
 The document will describe existing practice as well as define
 recommendations for future implementations.
