Totally off-topic, but it hits my mind right now. We are receiving a big 
amount of version queries on our public dns infra from a broad range of 
amazon ips - completely random from (just to show briefly some networks):

...
34.192.0.0/14
34.207.211.0/24
34.209.21.0/24
34.209.5.0/24
35.166.12.0/24
...
52.0.0.0/9
52.88.0.0/13
52.192.0.0/9
54.89.54.0/24
54.144.0.0/12
54.197.33.0/24
...

Is some one getting the same door knocks?
