IPv4 address Fetch Subrequest

Hi,

Is there a list of IPs (ipv4) workers use to to their subrequests with fetch? The API where I want to send API calls to, needs to allowlist the IPs where the calls are coming from.

I can’t add all the IPs from Cloudflare, because that’s a bit much :wink:

Thanks a lot
Best regards
Bert

Why does the number of IPs matter? Even if it was only one IP, that would still allow every Cloudflare user to access the API if it does not perform proper authentication.
