Our docker environment does not have any internet connection for security reasons.
Is there an IP list for downloading docker images?

Docker hub runs on AWS ELB and doesn't use any static IP address, so whitelisting the docker image repo IP is not a workable solution
Option 1) whitelist the dockerhub hosts.
Option 2) have an internal image registry, download the image manually and upload it to their internal registry server.
