mDNS (Multicast DNS)

mDNS (Multicast DNS) is a network protocol that allows devices on the same local network to discover and communicate with each other using human-readable names instead of IP addresses. It works by broadcasting queries and responses within a local network multicast group, enabling devices like printers, computers, and smart home gadgets to find and identify each other automatically without a central DNS server. This simplifies network setup and device connectivity, making it easier to manage devices in environments such as homes and small offices while maintaining reliable local communication.
