What is mdnsd android?

mDNSd (Multicast DNS Daemon) is a service running on Android devices that enables devices to discover and communicate with other devices on the network without requiring manual configuration or a central DNS server.

mDNSd allows devices to advertise their services and host names on the network using multicast DNS (mDNS), which is a protocol for resolving hostnames to IP addresses without the need for a DNS server. It also allows devices to browse and discover network services being offered by other devices on the network.

mDNSd is an important feature of Android’s networking stack, as it allows for easy discovery and connectivity of devices on local networks, making it easier for users to access and control their devices from their mobile devices.

Furthermore, it is worth mentioning that mDNSd needs to be enabled to use Google’s Chromecast feature, which allows users to stream media from their Android devices to a Chromecast device on their network.
