    :param VpcIds: One or more VPC IDs.
            Default: Describes all your VPCs.

    :type Filters: list
    :param Filters: One or more filters.
            cidr - The 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 ).
            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.
            state - The state of the VPC (pending | available ).
            tag :key =*value* - The key/value combination of a tag assigned to the resource. Specify the key of the tag in the filter name and the value of the tag in the filter value. For example, for the tag Purpose=X, specify tag:Purpose for the filter name and X for the filter value.
            tag-key - The key of a tag assigned to the resource. This filter is independent of the tag-value filter. For example, if you use both the filter 'tag-key=Purpose' and the filter 'tag-value=X', you get any resources assigned both the tag key Purpose (regardless of what the tag's value is), and the tag value X (regardless of what the tag's key is). If you want to list only resources where Purpose is X, see the tag :key =*value* filter.
            tag-value - The value of a tag assigned to the resource. This filter is independent of the tag-key filter.
            vpc-id - The ID of the VPC.
            (dict) --A filter name and value pair that is used to return a more specific list of results. Filters can be used to match a set of resources by various criteria, such as tags, attributes, or IDs.
            Name (string) --The name of the filter. Filter names are case-sensitive.
            Values (list) --One or more filter values. Filter values are case-sensitive.
