Our IT department is asking for confluence's IP addresses

[David Dyck]

I asked our IT department how to avoid Notifications from Confluence triggering the dire warnings when we get mail from confluence

The message looks something like this
   This message originated from the outside of our organization and was sent as ...  201701confluence.atlassian.net Be CAUTIOUS, as there is a HIGH CHANCE of this being a SPOOFED message from an ATTACKER. If you are unsure, please contact your local IT Support Staff.

What is the range of IP addresses used the confluence email notification sending computers?

I like the email, but not the spoofing warnings, so I would rather not disable them, like this is described here:   https://community.atlassian.com/t5/Jira-Service-Desk-questions/Disabling-Address-Spoofing-in-Notifications/qaq-p/616015
