## What A publishable range of external IP addresses for Buildkite that isn’t all of Amazon. Eg [Zendesk](https://support.zendesk.com/hc/en-us/articles/203660846-Configuring-your-firewall-for-use-with-Zendesk), [Travis](https://docs.travis-ci.com/user/ip-addresses/), [Github](https://help.github.com/en/articles/about-githubs-ip-addresses) etc. ## Why Many organisations run egress firewalls that require whitelisting of CIDRs for external communications for security reasons. By having a publishable range of external IPs you make Buildkite palatable to the security engineers in those organisations. ---

👋 Howdy @mtcmorris! Fancy seeing you here!! Good call on this one. This is something we’ve been discussing internally for aaages. Amazon hasn’t really given us any good tools to address this, but I think that’s about to change. **[…REDACTED…]** I’ll do some poking internally and see where we’re up to with it. ---

Hi! Are there any updates to this? All webhook notifications are 401ing because I can’t whitelist Buildkite. ---

Hi @dnguyen, It’s not documented anywhere yet, but we have an API endpoint here which might help: [https://api.buildkite.com/v2/meta](https://api.buildkite.com/v2/meta) `webhook_ips` is a list of CIDRs which we will send webhooks from. Do you think that will work for you? Nik ---

FYI (@dnguyen and anybody else interested): The IP addresses returned from [https://api.buildkite.com/v2/meta](https://api.buildkite.com/v2/meta) have changed as per [New outbound IP addresses](https://buildkite.com/changelog/118-new-outbound-ip-addresses) We’ll be switching to the new IP addresses in the coming two weeks.
