Fetch AWS IP ranges from official JSON source
npm install aws-ip-rangesFetch AWS's IP ranges from their official JSON source, for whatever configuration needs you have. See https://ip-ranges.amazonaws.com/ip-ranges.json for fields for available filter fields.
Valid examples:
``javascript
// Get all AWS IP ranges
awsIpRanges();
// Just Cloudfront ranges
awsIpRanges('CLOUDFRONT');
// Cloudfront and EC2
awsIpRanges(['CLOUDFRONT', 'EC2']);
// Cloudfront eu-west-1
awsIpRanges({
service: 'CLOUDFRONT',
region: 'eu-west-1'
});
// Anything in US regions
awsIpRanges({
region: /^us-/
});
// Arbitrary functions
awsIpRanges(function(range) {
return myProxyList.indexOf(range.ip_prefix || range.ipv6_prefix) > -1;
});
// Combine approaches as you need. Ranges are returned if any element matches.
awsIpRanges([
'CLOUDFRONT',
{region: 'us-east-1'},
function(range) { return range.ip_prefix && range.ip_prefix.split('.')[2] < 200}
]);
`
Output is just a list of CIDRs:
`javascript`
[
"2a05:d018::/36",
"216.137.32.0/19",
// ...
]
You can change where the cache file is stored; use the environment variable AWS_IP_RANGES_CACHE_FILE_PATH or call awsIpRanges.setCacheFilePath(path).
