**To modify the CIDR allocated to a resource** The following ``modify-ipam-resource-cidr`` example modifies a resource CIDR. (Linux):: aws ec2 modify-ipam-resource-cidr \ --current-ipam-scope-id ipam-scope-02fc38cd4c48e7d38 \ --destination-ipam-scope-id ipam-scope-0da34c61fd189a141 \ --resource-id vpc-010e1791024eb0af9 \ --resource-cidr 10.0.1.0/24 \ --resource-region us-east-1 \ --monitored (Windows):: aws ec2 modify-ipam-resource-cidr ^ --current-ipam-scope-id ipam-scope-02fc38cd4c48e7d38 ^ --destination-ipam-scope-id ipam-scope-0da34c61fd189a141 ^ --resource-id vpc-010e1791024eb0af9 ^ --resource-cidr 10.0.1.0/24 ^ --resource-region us-east-1 ^ --monitored Output:: { "IpamResourceCidr": { "IpamId": "ipam-08440e7a3acde3908", "IpamScopeId": "ipam-scope-0da34c61fd189a141", "IpamPoolId": "ipam-pool-0533048da7d823723", "ResourceRegion": "us-east-1", "ResourceOwnerId": "123456789012", "ResourceId": "vpc-010e1791024eb0af9", "ResourceCidr": "10.0.1.0/24", "ResourceType": "vpc", "ResourceTags": [ { "Key": "Environment", "Value": "Preprod" }, { "Key": "Owner", "Value": "Build Team" } ], "IpUsage": 0.0, "ComplianceStatus": "noncompliant", "ManagementState": "managed", "OverlapStatus": "overlapping", "VpcId": "vpc-010e1791024eb0af9" } } For more information on moving resources, see `Move resource CIDRs between scopes <https://docs.aws.amazon.com/vpc/latest/ipam/move-resource-ipam.html>`__ in the *Amazon VPC IPAM User Guide*.
