OpenSRS IP Whitelist.

Cloudflare Workers send every domain lookup from these egress IP ranges. Add them to your OpenSRS reseller control panel so requests aren’t rejected.

Where to add these in OpenSRS

  1. Log in to your OpenSRS Reseller Control Panel.
  2. Go to Profile → Access (or API Access → IP Restrictions).
  3. Add each CIDR range below one at a time, or paste the comma-separated list.
  4. Save and wait ~60 seconds for the change to propagate.
  5. Return to your site and test a domain search to confirm lookups succeed.

OpenSRS treats unrecognized IPs as authentication failures, which look exactly like bad credentials. If your lookups are returning 500s even with correct keys, this whitelist is almost certainly the fix.
