Subnet¶

class oci.core.models.Subnet(**kwargs)¶

Bases: object

A logical subdivision of a VCN. Each subnet consists of a contiguous range of IP addresses that do not overlap with other subnets in the VCN. Example: 172.16.1.0/24. For more information, see Overview of the Networking Service and VCNs and Subnets.

To use any of the API operations, you must be authorized in an IAM policy. If you’re not authorized, talk to an administrator. If you’re an administrator who needs to write policies to give users access, see Getting Started with Policies.

Example: {“Operations”: {“CostCenter”: “42”}}

Returns:	The defined_tags of this Subnet.
Return type:	dict(str, dict(str, object))

dhcp_options_id¶

Returns:	The display_name of this Subnet.
Return type:	str

dns_label¶

Gets the dns_label of this Subnet. A DNS label for the subnet, used in conjunction with the VNIC’s hostname and VCN’s DNS label to form a fully qualified domain name (FQDN) for each VNIC within this subnet (for example, bminstance1.subnet123.vcn1.oraclevcn.com). Must be an alphanumeric string that begins with a letter and is unique within the VCN. The value cannot be changed.

The absence of this parameter means the Internet and VCN Resolver will not resolve hostnames of instances in this subnet.

For more information, see DNS in Your Virtual Cloud Network.

Example: subnet123

Returns:	The dns_label of this Subnet.
Return type:	str

freeform_tags¶

Gets the freeform_tags of this Subnet. Free-form tags for this resource. Each tag is a simple key-value pair with no predefined name, type, or namespace. For more information, see Resource Tags.

Example: {“Department”: “Finance”}

Returns:	The freeform_tags of this Subnet.
Return type:	dict(str, str)

id¶

[Required] Gets the id of this Subnet. The subnet’s Oracle ID (OCID).

Returns:	The id of this Subnet.
Return type:	str

ipv6_cidr_block¶

Gets the ipv6_cidr_block of this Subnet. For an IPv6-enabled subnet, this is the IPv6 prefix for the subnet’s IP address space. The subnet size is always /64. See IPv6 Addresses.

Example: 2001:0db8:0123:1111::/64

Returns:	The ipv6_cidr_block of this Subnet.
Return type:	str

ipv6_cidr_blocks¶

Returns:	The ipv6_cidr_blocks of this Subnet.
Return type:	list[str]

ipv6_virtual_router_ip¶

Gets the ipv6_virtual_router_ip of this Subnet. For an IPv6-enabled subnet, this is the IPv6 address of the virtual router.

Returns:	The ipv6_virtual_router_ip of this Subnet.
Return type:	str

lifecycle_state¶

[Required] Gets the lifecycle_state of this Subnet. The subnet’s current state.

Allowed values for this property are: “PROVISIONING”, “AVAILABLE”, “TERMINATING”, “TERMINATED”, “UPDATING”, ‘UNKNOWN_ENUM_VALUE’. Any unrecognized values returned by a service will be mapped to ‘UNKNOWN_ENUM_VALUE’.

Returns:	The lifecycle_state of this Subnet.
Return type:	str

prohibit_internet_ingress¶

Gets the prohibit_internet_ingress of this Subnet. Whether to disallow ingress internet traffic to VNICs within this subnet. Defaults to false.

For IPV4, prohibitInternetIngress behaves similarly to prohibitPublicIpOnVnic. If it is set to false, VNICs created in this subnet will automatically be assigned public IP addresses unless specified otherwise during instance launch or VNIC creation (with the assignPublicIp flag in CreateVnicDetails). If prohibitInternetIngress is set to true, VNICs created in this subnet cannot have public IP addresses (that is, it’s a privatesubnet).

For IPv6, if prohibitInternetIngress is set to true, internet access is not allowed for any IPv6s assigned to VNICs in the subnet. Otherwise, ingress internet traffic is allowed by default.

Example: true

Returns:	The prohibit_internet_ingress of this Subnet.
Return type:	bool

prohibit_public_ip_on_vnic¶

Gets the prohibit_public_ip_on_vnic of this Subnet. Whether VNICs within this subnet can have public IP addresses. Defaults to false, which means VNICs created in this subnet will automatically be assigned public IP addresses unless specified otherwise during instance launch or VNIC creation (with the assignPublicIp flag in CreateVnicDetails). If prohibitPublicIpOnVnic is set to true, VNICs created in this subnet cannot have public IP addresses (that is, it’s a private subnet).

Example: true

Returns:	The prohibit_public_ip_on_vnic of this Subnet.
Return type:	bool

route_table_id¶

[Required] Gets the route_table_id of this Subnet. The OCID of the route table that the subnet uses.

Returns:	The route_table_id of this Subnet.
Return type:	str

security_list_ids¶

Gets the security_list_ids of this Subnet. The OCIDs of the security list or lists that the subnet uses. Remember that security lists are associated with the subnet, but the rules are applied to the individual VNICs in the subnet.

Returns:	The security_list_ids of this Subnet.
Return type:	list[str]

subnet_domain_name¶

Gets the subnet_domain_name of this Subnet. The subnet’s domain name, which consists of the subnet’s DNS label, the VCN’s DNS label, and the oraclevcn.com domain.

For more information, see DNS in Your Virtual Cloud Network.

Example: subnet123.vcn1.oraclevcn.com

Returns:	The subnet_domain_name of this Subnet.
Return type:	str

Example: 2016-08-25T21:10:29.600Z

Returns:	The time_created of this Subnet.
Return type:	datetime
