Bonjour is Apple's protocol for service discovery. It is lightweight and works over UDP. Bonjour implements a Multicast Domain Name System (mDNS) service without requiring a conventional DNS server.
Bonjour comprises:
- host discovery: finding the IP addresses of
.localdevices - service discovery: listing the capabilities of the devices
Bonjour is implemented in Linux systems under the name Avahi. There is also a Windows implementation of Bonjour.
Multicast frames
The mDNS frames are sent to the multicast address 01:00:5E:00:00:FB / 224.0.0.251, from and to port 5353.
Bonjour frames are filtered in Wireshark with the help of the expression:
ip.version==4 and udp.port==5353
Host discovery
Typing in a terminal
ping fpga1.diploma.local
