Recommended Actions

SOC Analyst Guidance:

1. No immediate blocking required - IP operates as legitimate cloud infrastructure

2. Monitor DNSBL listing - Investigate why 1 of 8 lists flags this IP

3. Allow HTTPS traffic - Standard cloud service port 443

4. No firewall rules - Standard egress allowed for cloud infrastructure

5. No IP reputation filtering - Low risk profile appropriate for whitelist consideration

Conclusion

34.156.187.171 is a benign Google Cloud Platform address supporting web services. The single DNSBL listing warrants minimal investigation but does not indicate active malicious behavior. No SOC blocking or filtering actions recommended. This IP represents normal cloud infrastructure operations rather than a threat source.
