MS Edge Port 5353

We are implementing MS Edge, but I see it's using UDP 5353, mDNS.  Anyone know why it's using that port?

Thank you!

mDNS stands for Multicast DNS which usually uses UDP5353. This is expected. (DNS uses port 53)
Usually, Apple Bonjour and Linux avahi-daemon services use mDNS to discover network peripherals within the local network.

The mDNS protocol is published as RFC 6762, uses IP multicast User Datagram Protocol (UDP) packets, and is implemented by the Apple Bonjour and open source Avahi software packages. Android contains an mDNS implementation. mDNS has also been implemented in Windows 10, initially limited to discovering networked printers, later becoming capable of resolving hostnames as well.
