- AWS enterprise VPC
http proxy exists
Without the HTTP proxy, curl http://169.254.169.254/lastest/meta-data successful, but disconnect to the Internet. This IP address is not Category A, B, C. Use this URI to get the meta-data from AWS.
With the HTTP proxy, curl the same URI failed, but can connect to Intenet.
So I was thinking the reason. Per my understanding,
If there is not HTTP proxy, a URI firstly get the IP from DNS, then based on the route table to send this request to Internet or Ethernet. If there is HTTP proxy, from which stage the request will be sent to HTTP proxy?
Without DNS stage, the URI is directly sent to HTTP proxy and do the DNS work in HTTP proxy?
So confusing around this...
