IP allow list now machine-readable; firewall updates automatable

October 10, 2025Auth0 Changelog
From the original release note

We are excited to announce an improvement that makes it faster and easier for you to keep your firewall configurations up-to-date.

Our IP allow list for Auth0's Public Cloud regions is now available in a standardized, machine-readable format. This new format is designed to help you automate updates and ensure the most accurate configuration for your firewall.

What this means for you:

  • Automation: You can now programmatically fetch and parse the list, eliminating the need for manual updates.
  • Accuracy: The structured data ensures you're always using the latest and most accurate IP addresses.
  • Clarity: The changelogs highlight specific additions and removals, so you can easily see what has been updated.

You can access this information at: https://cdn.auth0.com/ip-ranges.json

For more details, please see our documentation on IP allow list.
