Aws_Public_Ips - Fetch All Public IP Addresses Tied To Your AWS Account

aws_public_ips is a tool to fetch all public IP addresses (both IPv4/IPv6) associated with an AWS account.

It can be used as a library and as a CLI, and supports the following AWS services (all with both Classic & VPC flavors):

APIGateway
CloudFront
EC2 (and as a result: ECS, EKS, Beanstalk, Fargate, Batch, & NAT Instances)
ElasticSearch
ELB (Classic ELB)
ELBv2 (ALB/NLB)
Lightsail
RDS
Redshift

If a service isn't listed (S3, ElastiCache, etc) it's most likely because it doesn't have anything to support (i.e. it might not be deployable publicly, it might have all ip addresses resolve to global AWS infrastructure, etc).

Quick start
Install the gem and run it:

$ gem install aws_public_ips
 
 # Uses default ~/.aws/credentials
 $ aws_public_ips
 52.84.11.13
 52.84.11.83
 2600:9000:2039:ba00:1a:cd27:1440:93a1
 2600:9000:2039:6e00:1a:cd27:1440:93a1
 
 # With a custom profile
 $ AWS_PROFILE=production aws_public_ips
 52.84.11.159

Environment variables:

AWS_ACCESS_KEY_ID
AWS_SECRET_ACCESS_KEY
AWS_REGION
AWS_PROFILE

Shared credentials files:

~/.aws/credentials
~/.aws/config

Instance profile via metadata endpoint (if running on EC2, ECS, EKS, or Fargate)

For more information see the AWS SDK documentation on configuration.

IAM permissions
To find the public IPs from all AWS services, the minimal policy needed by your IAM user is:

{
   "Version": "2012-10-17",
   "Statement": [
     {
       "Effect": "Allow",
       "Action": [
         "apigateway:GET",
         "cloudfront:ListDistributions",
         "ec2:DescribeInstances",
         "elasticloadbalancing:DescribeLoadBalancers",
         "lightsail:GetInstances",
         "lightsail:GetLoadBalancers",
         "rds:DescribeDBInstances",
         "redshift:DescribeClusters"
       ],
       "Resource": "*"
     }
   ]
 }
