Control which IP version Discovery populates on a Network Adapter CI during Linux, Windows, and Solaris discovery.

## Before you begin

Verify that you have at least version 6.32.0 of Visibility Content.

Role required: discovery_admin

## About this task

When a network adapter supports both IPv4 and IPv6, Discovery populates the IP Address \[ip_address\] field on the Network Adapter \[cmdb_ci_network_adapter\] CI with one IP address. Before Visibility Content version 6.32.0, Discovery selected the value randomly. Starting from this release, IPv4 is populated by default. Use the network_adaptor_preferred_ip_version MID Server property to specify which IP version
to populate.{#set-network-adapter-preferred-ip__set-network-adapter-preferred-ip-context-1}

## Procedure

1. Navigate to AllMID ServerProperties.
2. In the Name column, search for <kbd class="ph userinput">network_adaptor_preferred_ip_version</kbd>.
3. Select the network_adaptor_preferred_ip_version property.
4. In the Value field, enter the accepted value for the IP version to populate.  
   Values are case-sensitive. Use only the accepted values listed in the table. {#set-network-adapter-preferred-ip__table-ip-version-values__entry__2}

   | IP version | Accepted values |
   |-|-|
   | IPv4 | ipv4, IPv4, or v4. |
   | IPv6 | ipv6, IPv6, or v6. |
   [Table 1. Accepted IP version values]

   {#set-network-adapter-preferred-ip__table-ip-version-values}
5. Select Update.
{#set-network-adapter-preferred-ip__steps_bbn_2gz_fjc}

## What to do next

Run discovery again or wait for the scheduled run to apply the changes.{#set-network-adapter-preferred-ip__set-network-adapter-preferred-ip-postreq-1}
