How this list is used

These are allowlist ranges. Webhooks, CI runners, integrations and API callbacks arrive from here, and a WAF or IP restriction that does not know about them will drop deliveries quietly — the sending service retries, gives up, and you find out days later that a queue stopped moving. Allowlist ahead of your bot rules, and keep it fresh: these ranges change more often than infrastructure ranges do.
