The mDNSResponder project is a component of Bonjour, Apple's ease-of-use IP

Apple's Bonjour software derives from the ongoing standardization work of the

The Zeroconf Working Group has identified three requirements for Zero
|
|
|
|
|
Configuration Networking:
|
|
|
|
|
1. An IP address (even when there is no DHCP server to assign one)
|
|
|
|
|
2. Name-to-address translation (even when there is no DNS server)
|
|
|
|
|
3. Discovery of Services on the network (again, without infrastucture)
|
|
|
|
|
|
|
|
|
|
Requirement 1 is met by self-assigned link-local addresses, as
|
|
|
|
|
described in "Dynamic Configuration of IPv4 Link-Local Addresses"
|
|
|
|
|
<http://files.zeroconf.org/draft-ietf-zeroconf-ipv4-linklocal.txt>
|
|
|
|
|
|
|
|
|
|
Requirement 2 is met by sending DNS-like queries via Multicast (mDNS).

Requirement 3 is met by DNS Service Discovery (DNS-SD).

|
|
|
|
|
Self-assigned link-local address capability has been available since
|
|
|
|
|
1998, when it first appeared in Windows '98 and in Mac OS 8.5.
|
|
|
|
|
Implementations for other platforms also exist.
