oci_core_vcn

This resource provides the Vcn resource in Oracle Cloud Infrastructure Core service.

The VCN automatically comes with a default route table, default security list, and default set of DHCP options. For managing these resources, see Managing Default VCN Resources

Creates a new Virtual Cloud Network (VCN). For more information, see VCNs and Subnets.

For the VCN, you specify a list of one or more IPv4 CIDR blocks that meet the following criteria:

For a CIDR block, Oracle recommends that you use one of the private IP address ranges specified in RFC 1918 (10.0.0.0/8, 172.16⁄12, and 192.168⁄16). Example: 172.16.0.0/16. The CIDR blocks can range from /16 to /30.

For the purposes of access control, you must provide the OCID of the compartment where you want the VCN to reside. Consult an Oracle Cloud Infrastructure administrator in your organization if you’re not sure which compartment to use. Notice that the VCN doesn’t have to be in the same compartment as the subnets or other Networking Service components. For more information about compartments and access control, see Overview of the IAM Service. For information about OCIDs, see Resource Identifiers.

You may optionally specify a display name for the VCN, otherwise a default is provided. It does not have to be unique, and you can change it. Avoid entering confidential information.

You can also add a DNS label for the VCN, which is required if you want the instances to use the Interent and VCN Resolver option for DNS in the VCN. For more information, see DNS in Your Virtual Cloud Network.

The VCN automatically comes with a default route table, default security list, and default set of DHCP options. The OCID for each is returned in the response. You can’t delete these default objects, but you can change their contents (that is, change the route rules, security list rules, and so on).

The VCN and subnets you create are not accessible until you attach an internet gateway or set up a Site-to-Site VPN or FastConnect. For more information, see Overview of the Networking Service.
