# Return One Network Peering Container

**GET /api/atlas/v2/groups/{groupId}/containers/{containerId}**

Returns details about one network peering container in one specified project. Network peering containers contain network peering connections. To use this resource, the requesting Service Account or API Key must have the Project Read Only role.

## Parameters

### Path parameters
- **groupId** (string)
  Unique 24-hexadecimal digit string that identifies your project. Use the [/groups](#tag/Projects/operation/listProjects) endpoint to retrieve all projects to which the authenticated user has access.

  **NOTE**: Groups and projects are synonymous terms. Your group id is the same as your project id. For existing groups, your group/project id remains the same. The resource and corresponding endpoints use the term groups.
- **containerId** (string)
  Unique 24-hexadecimal digit string that identifies the MongoDB Cloud network container.

### Query parameters
- **envelope** (boolean)
  Flag that indicates whether Application wraps the response in an `envelope` JSON object. Some API clients cannot access the HTTP response headers or status code. To remediate this, set envelope=true in the query. Endpoints that return a list of results use the results object as an envelope. Application adds the status parameter to the response body.
- **pretty** (boolean)
  Flag that indicates whether the response body should be in the prettyprint format.

OK

#### Body: application/vnd.atlas.2023-01-01+json (object)
- **id** (string)
  Unique 24-hexadecimal digit string that identifies the network peering container.
- **providerName** (string)
  Cloud service provider that serves the requested network peering containers.
- **provisioned** (boolean)
  Flag that indicates whether MongoDB Cloud clusters exist in the specified network peering container.
- **atlasCidrBlock** (string)
  IP addresses expressed in Classless Inter-Domain Routing (CIDR) notation that MongoDB Cloud uses for the network peering containers in your project. MongoDB Cloud assigns all of the project's clusters deployed to this cloud provider an IP address from this range. MongoDB Cloud locks this value if an M10 or greater cluster or a network peering connection exists in this project.

  These CIDR blocks must fall within the ranges reserved per RFC 1918. AWS and Azure further limit the block to between the `/24` and  `/21` ranges.

  To modify the CIDR block, the target project cannot have:

  - Any M10 or greater clusters
  - Any other VPC peering connections

   You can also create a new project and create a network peering connection to set the desired MongoDB Cloud network peering container CIDR block for that project. MongoDB Cloud limits the number of MongoDB nodes per network peering connection based on the CIDR block and the region selected for the project.

   **Example:** A project in an Amazon Web Services (AWS) region supporting three availability zones and an MongoDB CIDR network peering container block of limit of `/24` equals 27 three-node replica sets.
- **azureSubscriptionId** (string)
  Unique string that identifies the Azure subscription in which the MongoDB Cloud VNet resides.
- **region** (string)
  Azure region to which MongoDB Cloud deployed this network peering container.
- **vnetName** (string)
  Unique string that identifies the Azure VNet in which MongoDB Cloud clusters in this network peering container exist. The response returns **null** if no clusters exist in this network peering container.
