DNS-SD (DNS-Based Service Discovery)

DNS-Based Service Discovery (DNS-SD) is a protocol that allows devices on a local network to find and connect to services automatically, like printers, cameras, or media servers. It works by using familiar DNS (Domain Name System) technology to advertise and locate services without manual configuration. When a device joins the network, it announces what services it offers; other devices can then discover these services easily. This makes network setup seamless and dynamic, enabling devices to work together effortlessly without users needing to specify IP addresses or configurations.
