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 Dicsovery (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. + +The mDNSResponder project allows us to meet requirements 2 and 3. +It provides the ability for the user to identify hosts using names +instead of dotted-decimal IP addresses, even if the user doesn't have a +conventional DNS server set up. It also provides the ability for the +user to discover what services are being advertised on the network, +without having to know about them in advance, or configure the machines. |
