Can't access EC2 meta-data with public ip??

Hi,

The reason is outlined here: https://docs.aws.amazon.com/AWSEC2/latest/UserGuide/instancedata-data-retrieval.html

The instance metadata can only be reached from the ec2 server as mentioned below:

The IP addresses are link-local addresses and are valid only from the instance. For more information, see Link-local address on Wikipedia.

Hope it clarifies
