Understanding Bonjour


Bonjour is Apple's implementation of Zero-configuration networking (Zeroconf), a group of technologies that includes service discovery, address assignment, and hostname resolution. Bonjour locates devices such as printers, other computers, and the services that those devices offer on a local network by using multicast Domain Name System (mDNS) service records. Bonjour’s Zero Configuration (Zeroconf) provides a way to configure and browse for services over IP networks without knowing a service’s name or IP address. Using Bonjour, users can connect on a network to share files, printers, and Internet connections without configuring subnet masks or DNS servers.

Why Would I Use Bonjour?

Bonjour is useful when you have a BYOD policy that enables users to use programs such as iTunes, iChat, Adobe Systems Creative Suite 3, Proteus, Adium, Fire, Pidgin, Skype, Vine Server, or TiVo. Bonjour also comes bundled with some third-party applications, such as Adobe's Photoshop CS3 suite, to take advantage of Zeroconf technology. College campuses are a typical user of Bonjour.

What Is Zero Configuration?

Zeroconf Neighborhood Explorer for Windows is the windows version of Bonjour that enables Apple products such as iPhones®, iPods, iTouch, and Apple TV use on the network. Services such as AirPlay and AirPrint can also be deployed on wireless networks. Zero configuration IP networking enables these users to find printers and share files.

How Do I Configure Bonjour on a Juniper Networks Network Using Network Director?

Since services provided by Bonjour can consume considerable resources, you will want to limit the services to named VLANs. A typical Bonjour configuration sequence is:
