AWS IP Range Filter
At one point I needed to take the list of IP ranges that Amazon uses with AWS and filter it to just show the ones I cared about, which at the time was to see what uses the service "AMAZON" in the region "us-east-1".
This is a Node.js implementation that accomplishes that task.
Install dependancies
Install the dependancies by running npm install.
Set what you're filtering by
Modify the index.js file and set the region to be the region you want to filter by, and service to be the service you want to filter by.
By default it will filter the list to the service "AMAZON" in the region "us-east-1". If that's what you need, move on to the next step. Otherwise, be sure to change those values.
The current list of valid regions include:
us-east-1
ap-northeast-1
ap-southeast-1
eu-west-1
us-west-1
us-west-2
eu-central-1
ap-southeast-2
sa-east-1
ap-northeast-2
GLOBAL
us-gov-west-1
cn-north-1
The current list of valid services include:
AMAZON
EC2
ROUTE53
ROUTE53_HEALTHCHECKS
CLOUDFRONT
Run the script
Execute the following command to run the script and retrieve, then filter the list:
node index.js
Within a few moments you should see a list that looks something like this:
...
205.251.247.0/24
205.251.248.0/24
205.251.255.0/24
207.171.160.0/20
207.171.176.0/20
216.182.224.0/20
Found 76 IP ranges for the AMAZON service in the us-east-1 region
