Different forwarder for certain response ip (result ip )

[Omid Kosari]

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 8.8.8.254
Server:  UnKnown
Address:  8.8.8.254

Non-authoritative answer:
Name:    newsroom.fb.com
Addresses:  1.2.3.4
          1.2.3.4

Note:1.2.3.4 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 .

Thanks
