Bonjour

Bonjour is Apple‘s implementation of zero-configuration networking (Zeroconf). Zeroconf is a group of technologies that include service discovery, address assignment, and hostname resolution. Bonjour locates devices such as printers, other computers, and services that these computers offer over a local network. Bonjour provides a general method to discover services on a local area network (LAN). It allows users to set up a network without any configuration. Services such as printers, scanners, and filesharing servers can be found using Bonjour. Bonjour only works within a single broadcast domain. However, with special DNS configuration, it can be extended to find services across broadcast domains.
