    Subnet Resource Properties

    To learn more about resource properties and how to use them, see Inputs and Outputs in the Architecture and Concepts docs.

    Inputs

    In Python, inputs that are objects can be passed either as argument classes or as dictionary literals.

    The Subnet resource accepts the following input properties:

    NetworkId string
    The UUID of the parent network. Changing this creates a new subnet.
    AllocationPools List<Pulumi.OpenStack.Networking.Inputs.SubnetAllocationPool>
    A block declaring the start and end range of the IP addresses available for use with DHCP in this subnet. Multiple allocation_pool blocks can be declared, providing the subnet with more than one range of IP addresses to use with DHCP. However, each IP range must be from the same CIDR that the subnet is part of. The allocation_pool block is documented below.
    Cidr string
    CIDR representing IP range for this subnet, based on IP version. You can omit this option if you are creating a subnet from a subnet pool.
    Description string
    Human-readable description of the subnet. Changing this updates the name of the existing subnet.
    DnsNameservers List<string>
    An array of DNS name server names used by hosts in this subnet. Changing this updates the DNS name servers for the existing subnet.
    DnsPublishFixedIp bool
    Whether to publish DNS records for IPs from this subnet. Defaults is false.
    EnableDhcp bool
    The administrative state of the network. Acceptable values are "true" and "false". Changing this value enables or disables the DHCP capabilities of the existing subnet. Defaults to true.
    GatewayIp string
    Default gateway used by devices in this subnet. Leaving this blank and not setting no_gateway will cause a default gateway of .1 to be used. Changing this updates the gateway IP of the existing subnet.
    IpVersion int
    IP version, either 4 (default) or 6. Changing this creates a new subnet.
    Ipv6AddressMode string
    The IPv6 address mode. Valid values are dhcpv6-stateful, dhcpv6-stateless, or slaac.
    Ipv6RaMode string
    The IPv6 Router Advertisement mode. Valid values are dhcpv6-stateful, dhcpv6-stateless, or slaac.
    Name string
    The name of the subnet. Changing this updates the name of the existing subnet.
    NoGateway bool
    Do not set a gateway IP on this subnet. Changing this removes or adds a default gateway IP of the existing subnet.
    PrefixLength int
    The prefix length to use when creating a subnet from a subnet pool. The default subnet pool prefix length that was defined when creating the subnet pool will be used if not provided. Changing this creates a new subnet.
    Region string
    The region in which to obtain the V2 Networking client. A Networking client is needed to create a Neutron subnet. If omitted, the region argument of the provider is used. Changing this creates a new subnet.
    SegmentId string
    The segment ID of the subnet. This is used to specify which segment the subnet belongs to when using Neutron's routed provider networks. Available when neutron segment extension is enabled.
    ServiceTypes List<string>
    An array of service types used by the subnet. Changing this updates the service types for the existing subnet.
    SubnetpoolId string
    The ID of the subnetpool associated with the subnet.
    Tags List<string>
    A set of string tags for the subnet.
    TenantId string
    The owner of the subnet. Required if admin wants to create a subnet for another tenant. Changing this creates a new subnet.
    ValueSpecs Dictionary<string, string>
    Map of additional options.
    NetworkId string
    The UUID of the parent network. Changing this creates a new subnet.
    AllocationPools []SubnetAllocationPoolArgs
    A block declaring the start and end range of the IP addresses available for use with DHCP in this subnet. Multiple allocation_pool blocks can be declared, providing the subnet with more than one range of IP addresses to use with DHCP.

    Default gateway used by devices in this subnet. Leaving this blank and not setting no_gateway will cause a default gateway of .1 to be used. Changing this updates the gateway IP of the existing subnet.
    ipVersion Number
    IP version, either 4 (default) or 6. Changing this creates a new subnet.
    ipv6AddressMode String
    The IPv6 address mode. Valid values are dhcpv6-stateful, dhcpv6-stateless, or slaac.
    ipv6RaMode String
    The IPv6 Router Advertisement mode. Valid values are dhcpv6-stateful, dhcpv6-stateless, or slaac.
    name String
    The name of the subnet. Changing this updates the name of the existing subnet.
    networkId String
    The UUID of the parent network. Changing this creates a new subnet.
    noGateway Boolean
    Do not set a gateway IP on this subnet. Changing this removes or adds a default gateway IP of the existing subnet.
    prefixLength Number
    The prefix length to use when creating a subnet from a subnet pool. The default subnet pool prefix length that was defined when creating the subnet pool will be used if not provided. Changing this creates a new subnet.
    region String
    The region in which to obtain the V2 Networking client. A Networking client is needed to create a Neutron subnet. If omitted, the region argument of the provider is used. Changing this creates a new subnet.
    segmentId String
    The segment ID of the subnet. This is used to specify which segment the subnet belongs to when using Neutron's routed provider networks. Available when neutron segment extension is enabled.
    serviceTypes List<String>
    An array of service types used by the subnet. Changing this updates the service types for the existing subnet.
    subnetpoolId String
    The ID of the subnetpool associated with the subnet.
    tags List<String>
    A set of string tags for the subnet.
    tenantId String
    The owner of the subnet. Required if admin wants to create a subnet for another tenant. Changing this creates a new subnet.
