I saw part of this before, but the range is larger than I thought. A few weeks ago this info was posted in another thread:
54.160.0.0/13 (54.160.0.0 - 54.167.255.255)

A lookup today gave me more:
54.160.0.0 - 54.175.255.255
54.160.0.0/12
RegDate: 2014-06-20

what about 54.176.0.0/12
are they adjacent

This thread is about the Manticore UA, I posted the IP info for that particular IP to save a trip, but the thread covering AWS ranges where you can check that is here: [webmasterworld.com...]

That link's in the OP but oddly, clicking either brings me back to this thread. (Something awry w/ the forwarding script? Anyway...) Here's the current AWS URL for copy-pasting pleasure:
