2nd scenario is mine . Upstream manipulated everything on 53 tcp/udp . Even
if i query a non-existent dns-server it returns result ;)
C:\WINDOWS\system32>nslookup newsroom.fb.com 126.96.36.199
Note:188.8.131.52 is not what they really return . I've changed it for privacy .
But it is one fixed ip address which returns in case of manipulation occurs

FYI https://en.wikipedia.org/wiki/QUIC uses udp 443 . Also i try to reduce
the queries over 443 with the way i asked in my first post .
