# ModifyIpamResourceDiscovery


Modifies a resource discovery. A resource discovery is an IPAM component that enables IPAM to manage and monitor resources that belong to the owning account.

## Request Parameters


The following parameters are for this specific action. For more information about required and optional parameters that are common to all actions, see [Common Query Parameters](CommonParameters.md).

 **AddOperatingRegion.N**   
Add operating Regions to the resource discovery. Operating Regions are AWS Regions where the IPAM is allowed to manage IP address CIDRs. IPAM only discovers and monitors resources in the AWS Regions you select as operating Regions.  
Type: Array of [AddIpamOperatingRegion](API_AddIpamOperatingRegion.md) objects  
Array Members: Minimum number of 0 items. Maximum number of 50 items.  
Required: No

 **AddOrganizationalUnitExclusion.N**   
Add an Organizational Unit (OU) exclusion to your IPAM. If your IPAM is integrated with AWS Organizations and you add an organizational unit (OU) exclusion, IPAM will not manage the IP addresses in accounts in that OU exclusion. There is a limit on the number of exclusions you can create. For more information, see [Quotas for your IPAM](https://docs.aws.amazon.com/vpc/latest/ipam/quotas-ipam.html) in the *Amazon VPC IPAM User Guide*.  
The resulting set of exclusions must not result in "overlap", meaning two or more OU exclusions must not exclude the same OU. For more information and examples, see the AWS CLI request process in [Add or remove OU exclusions ](https://docs.aws.amazon.com/vpc/latest/ipam/exclude-ous.html#exclude-ous-create-delete) in the *Amazon VPC User Guide*.
Type: Array of [AddIpamOrganizationalUnitExclusion](API_AddIpamOrganizationalUnitExclusion.md) objects  
Array Members: Minimum number of 0 items. Maximum number of 10 items.  
Required: No

 **Description**   
A resource discovery description.  
Type: String  
Required: No

 **DryRun**
