  1. Final Test

Default VPC vs Non-default VPC DNS

  • EC2 instance in Default VPC = AWS provides it with public and private DNS hostnames that correspond to the public IPv4 and private IPv4 addresses for the instance.

  • EC2 instance in non-default VPC = AWS provides the instance with a private DNS hostname only.

    • Public DNS hostname only if:

      • If you have set the DNS resolution and DNS hostnames to true.

      • If your instance has a public IPv4 address.
