 @param [Hash] options ({})
 @option options [Array<Types::Filter>] :filters
   One or more filters.

   * `cidr` - The primary IPv4 CIDR block of the VPC. The CIDR block you
     specify must exactly match the VPC's CIDR block for information to
     be returned for the VPC. Must contain the slash followed by one or
     two digits (for example, `/28`).

   * `cidr-block-association.cidr-block` - An IPv4 CIDR block associated
     with the VPC.

   * `cidr-block-association.association-id` - The association ID for an
     IPv4 CIDR block associated with the VPC.

   * `cidr-block-association.state` - The state of an IPv4 CIDR block
     associated with the VPC.

   * `dhcp-options-id` - The ID of a set of DHCP options.

   * `ipv6-cidr-block-association.ipv6-cidr-block` - An IPv6 CIDR block
     associated with the VPC.

   * `ipv6-cidr-block-association.association-id` - The association ID
     for an IPv6 CIDR block associated with the VPC.

   * `ipv6-cidr-block-association.state` - The state of an IPv6 CIDR
     block associated with the VPC.

   * `isDefault` - Indicates whether the VPC is the default VPC.

   * `owner-id` - The ID of the AWS account that owns the VPC.

   * `state` - The state of the VPC (`pending` \| `available`).

   * `tag`\:&lt;key&gt; - The key/value combination of a tag assigned to
     the resource. Use the tag key in the filter name and the tag value
     as the filter value. For example, to find all resources that have a
     tag with the key `Owner` and the value `TeamA`, specify `tag:Owner`
     for the filter name and `TeamA` for the filter value.

   * `tag-key` - The key of a tag assigned to the resource. Use this
     filter to find all resources assigned a tag with a specific key,
     regardless of the tag value.

   * `vpc-id` - The ID of the VPC.
 @option options [Array<String>] :vpc_ids
   One or more VPC IDs.

   Default: Describes all your VPCs.
 @option options [Boolean] :dry_run
   Checks whether you have the required permissions for the action,
   without actually making the request, and provides an error response.
   If you have the required permissions, the error response is
   `DryRunOperation`. Otherwise, it is `UnauthorizedOperation`.
