2018/04/19 - Amazon Elastic Compute Cloud - 1 updated api methods
Changes Added support for customers to see the time at which a Dedicated Host was allocated or released.
{'Hosts': {'AllocationTime': 'timestamp', 'ReleaseTime': 'timestamp'}}
Describes one or more of your Dedicated Hosts.
The results describe only the Dedicated Hosts in the region you're currently using. All listed instances consume capacity on your Dedicated Host. Dedicated Hosts that have recently been released will be listed with the state released .

availability-zone - The Availability Zone of the host.
client-token - The idempotency token you provided when you allocated the host.
host-reservation-id - The ID of the reservation assigned to this host.

(dict) --
A filter name and value pair that is used to return a more specific list of results from a describe operation. Filters can be used to match a set of resources by specific criteria, such as tags, attributes, or IDs. The filters supported by a describe operation are documented with the describe operation. For example:
DescribeAvailabilityZones
DescribeImages
DescribeInstances
DescribeKeyPairs
DescribeSecurityGroups
DescribeSnapshots
DescribeSubnets
DescribeTags
DescribeVolumes
DescribeVpcs
Name (string) --
The name of the filter. Filter names are case-sensitive.
Values (list) --
One or more filter values. Filter values are case-sensitive.
(string) --
list
The IDs of the Dedicated Hosts. The IDs are used for targeted instance launches.
(string) --
integer
The maximum number of results to return for the request in a single page. The remaining results can be seen by sending another request with the returned nextToken value. This value can be between 5 and 500; if maxResults is given a larger value than 500, you will receive an error. You cannot specify this parameter and the host IDs parameter in the same request.
string
The token to retrieve the next page of results.
