Public IP Address Ranges for the Oracle Services Network

The Oracle Services Network is a conceptual network in Oracle Cloud Infrastructure that is reserved for Oracle services. Following are the CIDR blocks of the Oracle Services Network in each region. This list is not expected to change frequently because the blocks were sized to accommodate additional future services.

ap-seoul-1
ap-tokyo-1
ca-toronto-1
eu-frankfurt-1
uk-london-1
us-ashburn-1
us-phoenix-1

Public IP Addresses for the Oracle YUM Repos

The Oracle YUM repos have regional public endpoints that follow this format:

yum-<region>.oracle.com

For example:

  • yum-ashburn.oracle.com (for region us-ashburn-1)
  • yum-frankfurt.oracle.com (for region eu-frankfurt-1)

You can use DNS lookup to determine the public IP address for each endpoint.
