# Add an Existing Tag to an Asset

Perform these steps to add an existing Asset Tag (AT) or IP Range Tag (IPR) to an asset.

1. Navigate to **Inventory** and select the appropriate asset list view page.
2. Select one or more rows in the asset list.

   On the **Unified Inventory** page, you can tag only one asset at a time. On the asset-specific pages (**Domains**, **Certificates**, **Owned IPv4 Ranges**, etc) you can apply a tag to multiple assets at once.
3. Right click and select **Assign Asset Tags** or **Assign IP Range Tags**, as appropriate.
4. Click in the **Add tag...** field and select an existing tag from the drop-down menu.
5. Click **Save**.

## Querying This Documentation
If you need additional information that is not directly available in this page, you can query the documentation dynamically by asking a question.

Perform an HTTP GET request on the current page URL with the `ask` query parameter, and the optional `goal` query parameter:

```
GET https://cortex-docs.paloaltonetworks.com/cortex-xpanse/inventory/asset-tagging/add-an-existing-tag-to-an-asset.md?ask=<question>&goal=<endgoal>
```

`ask` is the immediate question: it should be specific, self-contained, and written in natural language.
`goal` is optional and describes the broader end goal you are ultimately trying to accomplish on behalf of the user. GitBook uses it to tailor the answer towards what is most useful for that goal.

The response will contain a direct answer to the question and relevant excerpts and sources from the documentation.

Use this mechanism when the answer is not explicitly present in the current page, you need clarification or additional context, or you want to retrieve related documentation sections.
