What is Bonjour and what does it do?
Bonjour is a networking technology developed by Apple that enables automatic discovery of devices and services on a local area network (LAN). It simplifies the process of connecting using protocols like Internet Protocol (IP), without needing to enter IP addresses or configure devices manually. Bonjour is often used for printer discovery, sharing files, and connecting to various services across devices, making your networking experience more seamless.
In essence, Bonjour operates using multicast DNS (mDNS) which allows devices to announce their presence on a network and resolve hostnames to IP addresses. This protocol is particularly useful in environments with multiple devices, such as home networks or offices, where quick and easy access to shared resources is beneficial. It is commonly bundled with software applications that require network discovery, such as iTunes, Adobe Creative Cloud, and even some games.
