One or more filters.
availabilityZone - The Availability Zone for the subnet. You can also
use availability-zone as the filter name.
available-ip-address-count - The number of IP addresses in the subnet
that are available.
cidrBlock - The CIDR block of the subnet. The CIDR block you specify
must exactly match the subnet's CIDR block for information to be returned for the subnet. You can also use cidr or cidr-block as the filter names.
defaultForAz - Indicates whether this is the default subnet for the Availability
Zone. You can also use default-for-az as the filter name.
state - The state of the subnet (pending | available). subnet-id - The ID of the subnet. tag:key=value - The key/value combination of a tag assigned to the resource. 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 for the subnet.
