<p><b>New page</b></p><div>[[File:Apple_Bonjour_Icon.png|thumb|Apple_Bonjour_Icon]] '''Bonjour''' is a [[zeroconf]] (zero-configuration) [[networking]] technology developed by [[Apple Inc.]] It allows devices to automatically discover each other on a local network without the need for manual configuration or special [[DNS]] servers. Bonjour is built into [[macOS]], [[iOS]], and is also available for [[Microsoft Windows]].<br />
<br />
==Overview==<br />
Bonjour uses industry-standard [[IP]] protocols to allow devices to automatically discover each other. It primarily uses [[Multicast DNS]] (mDNS) to resolve hostnames to IP addresses within small networks that do not include a local name server. Bonjour also uses [[Service Discovery Protocol]] (SDP) to locate services such as [[printers]], [[file sharing]], and other network services.<br />
<br />
==History==<br />
Bonjour was first introduced by Apple in 2002 under the name "Rendezvous." It was later renamed to Bonjour in 2005. The technology has since been integrated into a wide range of Apple products and services, including [[AirPlay]], [[HomeKit]], and [[iTunes]].<br />
<br />
==Functionality==<br />
Bonjour enables automatic discovery of computers, devices, and services on IP networks. It is used extensively in [[home networking]] and small office environments to simplify the setup and configuration of network services. For example, Bonjour can be used to find and connect to network printers, share files, and stream media between devices.<br />
<br />
==Implementation==<br />
Bonjour is implemented using a combination of [[mDNS]] and [[DNS Service Discovery]] (DNS-SD). mDNS is used to resolve hostnames to IP addresses within a local network, while DNS-SD is used to discover services. Bonjour is designed to work with both [[IPv4]] and [[IPv6]] networks.<br />
<br />
==Applications==<br />
Bonjour is used in a variety of applications, including:<br />
* [[AirPrint]]: Allows wireless printing from Apple devices.<br />
* [[AirPlay]]: Enables streaming of audio and video between devices.<br />
* [[HomeKit]]: Provides a framework for home automation.<br />
* [[iTunes]]: Allows sharing of music libraries over a local network.<br />
<br />
==Compatibility==<br />
Bonjour is compatible with a wide range of operating systems, including [[macOS]], [[iOS]], and [[Windows]]. Apple provides a Bonjour SDK for developers to integrate Bonjour functionality into their applications.<br />
<br />
==Security==<br />
Bonjour includes several security features to protect against unauthorized access and ensure the integrity of network communications. These include support for [[TLS]] (Transport Layer Security) and [[SSL]] (Secure Sockets Layer) for encrypted connections.<br />
