# Create a Managed Network

# Create a Managed Network {#ariaid-title1}

Release version: Brazil  
Updated November 5, 2026  
![](https://www.servicenow.com/docs/portal-asset/ico-clock) 1 minute to read  
Create a Managed Network record to define a network scope that can be assigned to IP Address Blocks. A Managed Network value propagates to subnetworks and allocated IP records beneath the IP Address Block, and the same CIDR can
exist in different Managed Networks without conflict.

## Before you begin

Install network discovery
plugins.

Role required: `sn_ni_core.inventory_admin, sn_ni_core.inventory_agent, sn_ni_core.inventory_template_manager, sn_ni_core.telco_inventory_catalog_manager`.

## About this task

The Managed Network record is optional for IP Address Block creation. If you create an IP Address Block without a Managed Network, its CIDR must be globally unique across all unscoped IP Address Blocks. If you create an IP Address
Block with a Managed Network assigned, its CIDR must be unique within that Managed Network.

To learn more about the propagation rules, see [Managed Network form](https://www.servicenow.com/docs/U7oWXPsXVoVQW~X0DLk1xg "The Managed network form enables you to manage a network in the Telecommunications Network Inventory application.").

## Procedure

1. Navigate to WorkspacesNetwork Inventory Workspace or Service Operations Workspace.
2. Select the list icon, and then go to Inventory Number AllocationManaged Network.
3. Select New.
4. Under the Details tab, on the form, fill in the Name field.  
   All other fields on this form are optional.

   To learn more about the available fields, see [Managed Network form](https://www.servicenow.com/docs/U7oWXPsXVoVQW~X0DLk1xg "The Managed network form enables you to manage a network in the Telecommunications Network Inventory application.").
5. Add packs to this service by selecting Add Packs.
6. Add attachments, such as graphics or documents, by selecting the attachment icon in the right panel.
7. Select Save.
8. View the related network inventories by selecting the brick icon.  
   The Infrastructure Relationships section shows all the related network inventories grouped by the individual network asset instances.

## What to do next

Create an IP Address Block that uses this Managed Network. See [Create an IP Address Block record](https://www.servicenow.com/docs/LDyTRIfdxpn5GAuNOAA16w "Create an IP Address Block record to define a top-level IP address range, expressed in Classless Inter-Domain Routing (CIDR) notation. The block becomes the parent for one or more IP Subnetworks. Supports both IPv4 and IPv6.").

You can also review or update the fields, create a related tab record, or delete a record. To learn more, see [Update or delete a record of an inventory number allocation](https://www.servicenow.com/docs/sTtqbTd9ccHCiKOO6iQTUQ "Review, update, and delete a record of an IP address space element using the Telecommunications Network Inventory application.").
