**To get the history of a CIDR**
The following ``get-ipam-address-history`` example gets the history of a CIDR.
(Linux)::
aws ec2 get-ipam-address-history \
--cidr 10.0.0.0/16 \
--ipam-scope-id ipam-scope-02fc38cd4c48e7d38 \
--start-time 2021-12-08T01:00:00.000Z \
--end-time 2021-12-10T01:00:00.000Z
(Windows)::
aws ec2 get-ipam-address-history ^
--cidr 10.0.0.0/16 ^
--ipam-scope-id ipam-scope-02fc38cd4c48e7d38 ^
--start-time 2021-12-08T01:00:00.000Z ^
--end-time 2021-12-10T01:00:00.000Z
