+## CrateDB Cloud IP Addresses  
+
+This page provides the outbound IP addresses used by CrateDB Cloud across
+different regions and cloud providers. These IPs should be allowlisted if you
+use external services that require network access from CrateDB Cloud, 
+such as:  
+
+- **Import Jobs** (when pulling data from external sources)  
+- **Managed Integrations** (e.g., MongoDB CDC)  
+- **COPY FROM/TO** (e.g., AWS S3, Azure Blob Storage, Google Cloud Storage)  
+- **Snapshot Repositories** (for backups to object storage)  
+- **Foreign Data Wrappers** (when connecting to external databases via FDW)  
+
+### **Outbound IP Addresses**  
+
+:::{caution}
+CrateDB Cloud **may update outbound IPs periodically** as infrastructure evolves.   
+:::
