Disable mDNS in Edge 89.0.7774.63 for many Windows 10 machines

Occasional Visitor

I'm in an environment where I have to tightly control accessible logical network ports on all cyber assets.  After installing the new edge, I noticed that when running, it opens UDP 5353 for an mDNS capability.  I found the flag (#enable-webrtc-hide-local-ips-with-mdns) to disable that, but I need to do that for all machines and all users and I really don't want to have to visit each machine one at a time if possible.


Is there a registry setting, PowerShell command, etc that I could use to affect that change across all of the workstations?

Hello. updates come quickly - today I downloaded a new one maybe it will fix version 89.0.774.76 (official build) (64-bit version)
But I do not know!



make a shortcut on your clients' PCs pointing to this:

"C:\Program Files (x86)\Microsoft\Edge\Application\msedge.exe" --flag-switches-begin --enable-features=WebRtcHideLocalIpsWithMdns --flag-switches-end

deploy that shortcut using any management tool you use, sccm, intune, group policy etc.

that will launch Edge with that feature.
