In computing, Bonjour (formerly Rendezvous1) is Apple Inc.'s trade name for its implementation of Zeroconf, a service discovery protocol. Bonjour locates devices such as printers, other computers, and the services that those devices offer on a local network using multicast Domain Name System service records.

Macs (OSX 10.4+) come installed with dns-ds, which is a

Zero configuration networking (zeroconf), is a set of techniques that automatically creates a usable Internet Protocol (IP) network without manual operator intervention or special configuration servers. Zero configuration networking allows inexpert users to connect computers, networked printers, and other network devices and expect a functioning network to be established automatically. Without zeroconf, a user must either set up special services, like Dynamic Host Configuration Protocol (DHCP) and Domain Name System services (DNS), or set up each computer's network settings manually, which may be difficult or impossible for non-technical or novice users.
