## Request Parameters
<a name="API_ModifyIpamResourceDiscovery_RequestParameters"></a>

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 Amazon Regions where the IPAM is allowed to manage IP address CIDRs. IPAM only discovers and monitors resources in the Amazon 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 Amazon 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.amazonaws.cn/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.
