Mdnsresponder, short for multi-domain name server responder, is a free and open source system that allows you to forward (resolve) domain names. Forwarding makes it possible for your computer to find other computers on the Internet by creating an entry in its list of known hosts.
Mdnsresponder is a service that allows your Mac to respond to the multicast DNS (mDNS) requests. This service can be disabled by following these steps: “mdnsresponder mac disable”.
If you’re the inquisitive kind, you may have seen a process named Mdnsresponder running beneath the network tab if you open the activity monitor on your Mac.
At first look, you could think the process is malicious since it has transmitted and received a large amount of data in the form of packets. So, what exactly is a Mdnsresponder? Is it hazardous, or is it beneficial?
So, in this post, we’ll take a closer look at the Mdnsresponder and figure out why it’s operating on your Mac.

Apple built the Mdnsresponder, or multicast DNS responder, which is a network-based procedure. So, if you were concerned that the procedure was malevolent, you could rest easy.
The procedure is part of the Bonjour protocol, which is an open-source networking service that requires no setup. Overall, this protocol allows Apple products to talk with one other over a local network without the need for any settings.
So, whether you wish to connect to a printer or exchange files with a network storage device, the Mdnsresponder is making things happen in the background.
Both devices must follow the same criteria for device identification and communication in order to communicate with one other.
The Bonjour protocol is used by Apple to locate and configure devices on a local area network. Data is sent between devices via the Internet protocol once the devices have been recognized and setup.
Mdnsresponder.exe will be running in your task manager if you have Itunes installed on your Windows machine. This facilitates Itunes library sharing on Windows devices and demonstrates that the technique can be found on devices other than Apple devices.
The connecting devices must know each other’s IP addresses in order to communicate data through the Internet protocol. DNS servers are used to carry out this activity across the Internet. In the case of Bonjour, the Mdnsresponder is used to do this duty.

Let’s imagine you wish to transmit files from your laptop to your phone using Airplay. For this data to be sent, the laptop begins scanning for other devices on your local area network. The Mdnsresponder does this by sending multicast DNS queries to all devices on your network.
If a device on your network (such as your phone) is running the Bonjour protocol and has the same name as the DNS request, it will receive the request and respond with its IP address. The laptop will begin delivering data via the Internet protocol once it receives this information.
Despite the fact that the Mdnsresponder is required for communication across a local area network, you may kill it via the activity monitor. However, since it is a component of a crucial networking protocol, the procedure would restart.
Apple attempted to eliminate the Mdnsresponder responder in Mac OS Yosemite in 2014, however various issues were reported as a result of the change. As a result, Apple reintroduced the procedure in Mac OS El Capitan, which repaired over 300 issues. As a result, it’s reasonable to declare that Mdnsresponder should not be removed.

%SystemRoot%\system32\svchost.exe -k netsvcs
then paste it into the command prompt window by pressing CTRL+V. This will execute a system file called svchost.exe which is used for hosting your devices network profiles so you can use them when connecting to other devices over Bluetooth or Wi-Fi during an establishment process
What is mDNS Mac?
A: The mDNS protocol is a standard for discovery of networked devices using multicast DNS. It enables the automatic configuration of IP addresses and hostname to an attached device running Bonjour, Avahi or Zeroconf.
