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.
