NTAC Peering Working Group

[David Farmer <>]

Hi from Montreal and NANOG/ARIN,

I was at the DNS-OARC Fall 2015 conference over the weekend;

https://indico.dns-oarc.net/event/24/

At the mic in one of the Q&A sessions an Amazon guy mentioned that they 
had a json file with descriptions for all the IP ranges they advertise. 
 I though others would find it interesting and/or useful in optimizing 
their peering policies with I2 R&E, TR-CPS, and maybe Amazon as well.

I would really appreciate it if someone would use this to validate, and 
optimize if necessary, both the I2 R&E and TR-CPS backbone peering 
policies for Amazon.  Standard closest exit, may not be the most optimal 
routing policy and Amazon is important enough for all of us to do this 
extra level of work.

Thanks.

The direct link to the data is 
https://ip-ranges.amazonaws.com/ip-ranges.json. There's documentation 
available at 
http://docs.aws.amazon.com/general/latest/gr/aws-ip-ranges.html. We try 
to update that before advertising/using new prefixes, in general. Let me 
know if you have any other specific questions.
