# Design Assign IP Address Validation subflow

# Design Assign IP Address Validation subflow {#ariaid-title1}

Release version: Australia  
Updated March 12, 2026  
![](https://www.servicenow.com/docs/portal-asset/ico-clock) 1 minute to read  
The TNI Design Assign IP Address Validation subflow enables you to validate the IP address records in the Telecommunications Network Inventory application. You can use this flow action to configure the activities in a Design and Assign playbook for logical connection.
The TNI Design Assign IP Address Validation subflow validates whether the IP address records required for the Define IP address activity have already been used or not. If the IP addresses are already used, the subflow passes the
information.

## Roles and availability {#tni-design-assign-ip-address-validation-subflow__section_kfd_fdk_x5b}

An admin can add a subflow to a flow and define the configuration details of the flow. This Workflow Studio subflow is available in the Telecommunications Network Inventory application so that you can perform inventory-related data operations.

## Input fields {#tni-design-assign-ip-address-validation-subflow__section_xbc_vyp_x5b}

The following table lists the input fields in the TNI Design Assign IP Address Validation subflow and their descriptions.
