What ip and mac addresses should i send to cosume a web service from a docker container?

  docker, mac-address, web-services

I need to build a Python aplication and set up an associated machine that consume a web service on a daily basis from a secure organisation. They have asked me to provide an ip and mac addresses so they can add it to their allowed client list. I must deploy a docker container with the python aplication and it will have a public ip as explained by P Marecki (This will be the ip I will send).

My question is: which mac address should i send? The one associated to the machine that hosts the container or the cointainer mac?

Thanks in advance
