[Issue]: Firestick DNS querry spam

[cgutman]

I highly doubt this is a Moonlight bug. That hostname belongs to Microsoft and is used for their Internet connectivity testing. It's not contained anywhere inside any of Moonlight's source code. There are also tons of reports on the Internet of DNS query spam to dns.msftncsi.com, so it seems it's a relatively common issue.

The only hosts Moonlight will ever reach out to are *.moonlight-stream.org addresses for STUN and port blocking tests.

FWIW, I'm not seeing this behavior here on my network. I have my Android devices using a private DoT server and I don't see dns.msftncsi.com in the logs at all (which is expected since that's a Microsoft domain and Google uses other ones for Android).

The fact that it occurs when closing Moonlight is more evidence that it's something the OS is doing (such as trying to load new content when returning to the home launcher).

For that reason internet is not working for some time, until router clears DNS requests.

My guess is that you have the cause and effect reversed. I'll bet your connection goes down first, and that's why you get a flurry of Internet connectivity requests as apps try to load content, fail, and wait for connectivity to come back to retry.

DNS I mentioned is just info what I see, but can be also false positive as log may not be updated when DNS spam ocurs. What IS the issue is that DNS spam is only triggered when exiting app (sometimes also during runtime) version 12.0.1 and 12.0.2. Version 12.0 does not trigger it.

It may be (sure is) OS bug, but for some reason only last two versions triggers it. Did exit, streaming stop code changed?

I am available if you want me to do some additional test...
