This document is helpful: https://confluence.atlassian.com/bitbucket/what-are-the-bitbucket-cloud-ip-addresses-i-should-use-to-configure-my-corporate-firewall-343343385.html
but only really readable by a human. I want to update our firewalls automatically, or at least alert ourselves of changes to the Bitbucket IPs. Is there some API route I can hit for Bitbucket to determine changes to their IPs?
