+### Integrate the private endpoint with a private DNS zone
+
+After you create the private endpoint, you can integrate it with a private DNS zone by using the following Azure CLI script:
+
+```azurecli-interactive
+
+zoneName="privatelink.documents.azure.com"
+
+az network private-dns zone create --resource-group $ResourceGroupName \
+   --name  $zoneName
+
+az network private-dns link vnet create --resource-group $ResourceGroupName \
+   --zone-name  $zoneName\
+   --name myzonelink \
+   --virtual-network $VNetName \
+   --registration-enabled false 
+
+#Query for the network interface ID  
+networkInterfaceId=$(az network private-endpoint show --name $PrivateEndpointName --resource-group $ResourceGroupName --query 'networkInterfaces[0].id' -o tsv)
+ 
+# Copy the content for privateIPAddress and FQDN matching the Azure Cosmos account 
+az resource show --ids $networkInterfaceId --api-version 2019-04-01 -o json 
+ 
+#Create DNS records 
+az network private-dns record-set a create --name recordSet1 --zone-name privatelink.documents.azure.com --resource-group $ResourceGroupName
+az network private-dns record-set a add-record --record-set-name recordSet2 --zone-name privatelink.documents.azure.com --resource-group $ResourceGroupName -a <Private IP Address>
