Hi – Can you check behavior of the resolvers for the name techfund.comcast.com? It should return a CNAME and then that resolves an A record:

When I connect to the v6only or nat64 networks, I'm not seeing any DNS servers configured using Windows 10.  What mechanism is being used to configure the DNS servers on clients?

I'm seeing lots of not answered queries to 31.130.229.7  and 2001:67c:370:229::7
leading to slow network behavior. 
I'm on IETF-1a.x in Buckingham room.
