So the string breaks down into:

: To get the actual temporary keys (AccessKeyId, SecretAccessKey, and Token), you must append the role name returned by the first command to the end of the URL: Example: curl http://169.254.169 Troubleshooting Common Issues So the string breaks down into: import socket from urllib

The response contains:

Every EC2 instance runs a lightweight service that exposes instance metadata – information about the instance itself, such as its hostname, public IP, AMI ID, and, most critically, . The service is reachable only from within the instance via the non‑routable IP address 169.254.169.254 . This address is part of the IPv4 link‑local block ( 169.254.0.0/16 ), which is never forwarded by routers, ensuring that metadata queries cannot escape the instance’s local network.

: This part of the URL refers to the metadata service endpoint. The metadata service provides information about the instance, such as its ID, type, and IP address. Use roles that only allow the exact actions needed

Never assign an overly permissive role (e.g., AdministratorAccess ) to an EC2 instance. Use roles that only allow the exact actions needed. If an attacker steals credentials from a role that can only read one S3 bucket, the damage is contained.
