Port 5356

Port 5356 is used for the Multicast Domain Name System (mDNS) service. It is used for discovering and communicating with devices on a local network using their hostnames, rather than IP addresses. This port is often used by Apple’s Bonjour protocol, which allows devices like printers, speakers, and other network-connected devices to be easily discovered and accessed on a local network.
