AWS IP address utilities
Useful for checking if an IP address belongs to an AWS subnet. The gem automatically updates and publishes itself every day, publishing only takes place if the AWS IP ranges change.
The prefixes get retrieved from https://ip-ranges.amazonaws.com/ip-ranges.json
Installation
Add this line to your application's Gemfile:
gem 'aws_ip_utilities'
And then execute:
$ bundle
Or install it yourself as:
$ gem install aws_ip_utilities
Usage
You can check if an IP address belongs to AWS by doing a check:
AwsIpUtilities.aws_ip?(your_ip_addr) #=> true or false
Find out what region the IP is in:
AwsIpUtilities.region_for(your_ip_addr) #=> "eu-west-1"
and determine what service it provides:
AwsIpUtilities.service_for(your_ip_addr) #=> "CLOUDFRONT"
To make Rack::Request
trust all AWS machines as a proxies for determining the client IP (when it gets injected into X-Forwarded-For
) call the following method:
AwsIpUtilities.make_aws_rack_trusted_proxy!
Development

to install dependencies. Then, run rake spec
