Bonjour is

hostname resolution. Bonjour locates devices such as printers, other computers, and the services that those devices offer on a local network using multicast Domain Name System
(mDNS) service records.

The software comes built-in with Apple's macOS and iOS operating systems. Bonjour can also be installed onto computers running Microsoft Windows. Bonjour components may also be included within other software such as iTunes and Safari.

It was originally introduced in 2002 with

Mac OS X 10.2 with the name Rendezvous. It was renamed in 2005 to Bonjour following an out-of-court trademark dispute settlement.[1][2]

Overview

Bonjour provides a general method to discover services on a local area network. The software is widely used throughout macOS, and allows users to set up a network without any configuration. As of 2010 it is used to find printers and file-sharing servers.

Notable applications using Bonjour include:

Software such as

Bonjour Browser or iStumbler, both for macOS, can be used to view all services declared by these applications. Apple's "Remote" application for iPhone and iPod Touch also uses Bonjour to establish connection to iTunes libraries via Wi-Fi.[3]

Bonjour only works within a single broadcast domain, which is usually a small area, without special DNS configuration. macOS, Bonjour for Windows and AirPort Base Stations may be configured to use Wide Area Bonjour which allows for wide area service discovery via an appropriately configured DNS server.

Applications generally implement Bonjour services using standard

Solaris, VxWorks, and Windows
. Apple also provides a user-installable set of services called Bonjour for Windows and Java libraries.

Licensing

Bonjour is released under a terms-of-limited-use license by Apple. It is

licensing agreement. The source code for mDNSResponder is available under the Apache License.[4]

Naming

Apple originally introduced the Bonjour software in August 2002 as part of

Mac OS X 10.2 under the name "Rendezvous". On August 27, 2003 Tibco Software Inc announced that it had filed a lawsuit for trademark infringement.[5]
Tibco had an enterprise application integration product called TIBCO Rendezvous on the market since 1994 and stated that it had tried to come to an agreement with Apple Computer. In July 2004 Apple Computer and Tibco reached an out-of-court settlement;[6] specifics of the settlement were not released to the public. On April 12, 2005, Apple announced the renaming of Rendezvous to "Bonjour".[1]

The current name Bonjour is French for the morning or afternoon greeting, "good day". The previous name Rendezvous is French for "meeting", "appointment" or "date".[7]

Other implementations

Bonjour version 2.0, released on February 24, 2010, works with Microsoft Windows 2000, 2003, XP, Vista, 7, 8, 8.1, 10, and 11.

Java VMs.[8][9]

Some third-party applications, such as

also come bundled with Bonjour to take advantage of zeroconf technology.

Installers on Windows systems normally place Bonjour files in a folder called "Bonjour" within the "Program Files" folder. It modifies

Windows system-registry
entries related to internal network configuration and operation. Bonjour runs as mDNSResponder.exe. Communications across the network take place over UDP port 5353, which may require reconfiguring some personal or corporate firewalls that block Bonjour packets. A full installation of Bonjour for Windows will include a plug-in for Internet Explorer, a printer wizard, and the network communication services. Not all components are included when installed as part of a third-party application or as a component of other Apple software such as iTunes.

Some VPN clients are configured so that local network services are unavailable to a computer when VPN software is active and connected.[8] In such a case no local zeroconf services are available to Bonjour or any other zeroconf implementation.

In September 2008, two security vulnerabilities were found in Bonjour for Windows.[11] Certain installations of Bonjour for Windows lack an uninstaller and do not display a human-readable entry in the Windows services listing.[12]

In 32- and 64-bit releases of Windows 7, some older but still available versions of Bonjour services can disable all network connectivity by adding an entry of 0.0.0.0 as the default gateway. This was a bug reported in 2013.[13]

The open-source IM clients Pidgin, Kopete and Adium support the Bonjour IM protocol, as does the closed-source Trillian client.

Browsers

A number of browsers allow an end-user to graphically explore the devices found using Bonjour.

Discovery / Bonjour Browser

Discovery is a

Apple changed the protocol's name to Bonjour; since version 2.0, it has been renamed again, to Discovery. For certain protocols, double-clicking a list item will launch the associated helper. Version 1.5.6 was the first universal binary
release.

Future versions will allow users to completely define a service, instead of relying on the author to do so.

Bonjour Browser was recommended for

MacAddict
#123.

Discovery is available on the Apple App Store.[14]

JBonjourBrowser

A student research project at

GPL
.

JBonjourBrowser was built to emulate the functionality of Bonjour Browser, and at the same time work on multiple platforms. It requires Apple's Bonjour Java library to run.

Bonjour Browser for Windows

A native Windows application offers similar functions to Bonjour Browser for Mac OS. Bonjour Browser for Windows is offered for free by Hobbyist Software and HandyDev Software.

mDNSBrowser

A commercial implementation called mDNSBrowser is offered by Netputing Systems Inc.
