NAME
    gcloud alpha compute networks subnets expand-ip-range - expand the IP range
        of a Compute Engine subnetwork

SYNOPSIS
    gcloud alpha compute networks subnets expand-ip-range NAME
        --prefix-length=PREFIX_LENGTH [--region=REGION] [GCLOUD_WIDE_FLAG ...]

DESCRIPTION
    (ALPHA) gcloud alpha compute networks subnets expand-ip-range expands the
    IP range of a VPC subnetwork.

    For more information about expanding a subnet, see Expanding a primary IP
    range (https://cloud.google.com/vpc/docs/using-vpc#expand-subnet).

    This command doesn't work for secondary subnets or for subnets that are
    used exclusively for load balancer proxies. For more information, see
    Proxy-only subnets for load balancers
    (https://cloud.google.com/load-balancing/docs/l7-internal/proxy-only-subnets).

EXAMPLES
    To expand the IP range of SUBNET to /16, run:

        $ gcloud alpha compute networks subnets expand-ip-range SUBNET \
            --region=us-central1 --prefix-length=16

POSITIONAL ARGUMENTS
     NAME
        Name of the subnetwork to operate on.

REQUIRED FLAGS
     --prefix-length=PREFIX_LENGTH
        The new prefix length of the subnet. It must be smaller than the
        original and in the private address space 10.0.0.0/8, 172.16.0.0/12 or
        192.168.0.0/16 defined in RFC 1918.

OPTIONAL FLAGS
     --region=REGION
        Region of the subnetwork to operate on. If not specified, you might be
        prompted to select a region (interactive mode only).

        To avoid prompting when this flag is omitted, you can set the
        compute/region property:

            $ gcloud config set compute/region REGION

        A list of regions can be fetched by running:

            $ gcloud compute regions list

        To unset the property, run:

            $ gcloud config unset compute/region

        Alternatively, the region can be stored in the environment variable
        CLOUDSDK_COMPUTE_REGION.

GCLOUD WIDE FLAGS
    These flags are available to all commands: --access-token-file, --account,
    --billing-project, --configuration, --flags-file, --flatten, --format,
    --help, --impersonate-service-account, --log-http, --project, --quiet,
    --trace-token, --user-output-enabled, --verbosity.

    Run $ gcloud help for details.

NOTES
    This command is currently in alpha and might change without notice. If this
    command fails with API permission errors despite specifying the correct
    project, you might be trying to access an API with an invitation-only early
    access allowlist. These variants are also available:

        $ gcloud compute networks subnets expand-ip-range

        $ gcloud beta compute networks subnets expand-ip-range
