This topic provides information about public IP address ranges for services that are
deployed in Oracle Cloud Infrastructure. Allow traffic to these CIDR
blocks to ensure access to the services.
Endpoints for Oracle YUM repos are listed on this page. You can use DNS lookup to determine the public IP address for each endpoint.
Public IP Addresses for VCNs and the Oracle Services Network
Public IP address ranges for VCNs and the Oracle Services Network are published to a JSON file which you can download and view manually or consume programmatically.
The Oracle Services Network is a conceptual network in Oracle Cloud Infrastructure that is reserved for Oracle services. A service gateway offers private access to the Oracle Services Network from workloads in your VCN and your on-premises network. The published addresses correspond to the service CIDR label called All <region> Services in Oracle Services Network. For a list of the services available with a service gateway, see Service Gateway: Supported Cloud Services in Oracle Services Network.
You can poll the published file to check for new IP address ranges as frequently as every 24 hours. We recommend that you poll the published file at least weekly.
