Bonjour was used by apple to execute the zero-configuration networking. This service allows networking among various apple devices. It assists in discovering and connecting to multiple devices, including printers and other computers. Bonjour defeats the purpose of a dynamic host configuration protocol (DHCP). 

It uses a “link-local addressing” method, which can automatically assign IP addresses to local clients without needing DHCP.  Apart from this, services are offered on a local area network through mDNS server (Multicast Domain Name System Service) service records, ensuring the internet speed is not affected while taking support information.
