   &quot;consumerNetwork&quot;: &quot;A String&quot;, # Required. The name of the service consumer&#x27;s VPC network. The network must have an existing private connection that was provisioned through the connections.create method. The name must be in the following format: `projects/{project}/global/networks/{network}`, where {project} is a project number, such as `12345`. {network} is the name of a VPC network in the project.
   &quot;description&quot;: &quot;A String&quot;, # Optional. Description of the subnet.
   &quot;ipPrefixLength&quot;: 42, # Required. The prefix length of the subnet&#x27;s IP address range. Use CIDR range notation, such as `30` to provision a subnet with an `x.x.x.x/30` CIDR range. The IP address range is drawn from a pool of available ranges in the service consumer&#x27;s allocated range.
+  &quot;privateIpv6GoogleAccess&quot;: &quot;A String&quot;, # Optional. The private IPv6 google access type for the VMs in this subnet. For information about the access types that can be set using this field, see [subnetwork](https://cloud.google.com/compute/docs/reference/rest/v1/subnetworks) in the Compute API documentation.
   &quot;region&quot;: &quot;A String&quot;, # Required. The name of a [region](/compute/docs/regions-zones) for the subnet, such `europe-west1`.
   &quot;requestedAddress&quot;: &quot;A String&quot;, # Optional. The starting address of a range. The address must be a valid IPv4 address in the x.x.x.x format. This value combined with the IP prefix range is the CIDR range for the subnet. The range must be within the allocated range that is assigned to the private connection. If the CIDR range isn&#x27;t available, the call fails.
   &quot;requestedRanges&quot;: [ # Optional. The name of one or more allocated IP address ranges associated with this private service access connection. If no range names are provided all ranges associated with this connection will be considered. If a CIDR range with the specified IP prefix length is not available within these ranges, the call fails.
