You can use ACLI to quickly check where your DNS is pointed for domains hosted on Acquia with a short script (tested on Mac). This script will list each domain in your Acquia Cloud environment and then run a `dig` against each domain.
Step 1: Ensure that you have updated ACLI to the latest stable version.
Step 2: Copy and paste the script below replacing ___site___ and ___env___ with the sitename and environment for your application (this is typically the docroot and env).
for domain in $(acli api:environments:domain-list ___site___.___env___ | grep hostname | cut -d '"' -f 4); do echo $domain:; dig $domain +short echo "" done
