To patch a network-contained host, create or update a Containment Policy that allowlists the specific IP addresses of the patch management or update sources. Containment blocks most network traffic by design, so update jobs fail unless the required update infrastructure is explicitly permitted. The course guide calls out IP addresses for Windows Update or update sources, not FQDN-based allowlisting, as the supported containment-policy exception method. Content update policies are unrelated to allowing host network traffic during containment. IP Allowlist Management controls administrative access to Falcon from specific source IPs; it does not permit contained endpoints to reach patch servers. Therefore, the containment policy must allow the patch infrastructure IPs.
