DNS-SD (DNS Service Discovery)

DNS-SD, or DNS Service Discovery, is a technology that helps devices on a local network find services provided by other devices. Think of it like a directory that not only lists what services are available, such as printers or file sharing, but also helps devices discover how to connect to them. Instead of remembering complicated addresses or settings, devices can automatically locate and communicate with the services they need, making networking smoother and more user-friendly. DNS-SD is commonly used in home networks and by applications like AirPlay or printers that need to share resources effortlessly.
