| IPv6 Support                 | <p>Cortex Xpanse now supports the discovery and monitoring of IPv6 assets. Xpanse discovers new IPv6 assets through domain resolution using AAAA DNS records or customers can provide a list IPv6 addresses for monitoring.</p><p>A new Owned IPv6 Ranges page has been added to the Inventory, and an IPv6 field has been added to Services, Domains, Certificates, Owned Responsive IPs, Incidents, and Alerts pages. IPv6 search and filtering on these pages is supported. IPv6 data is included in dashboards, with some widgets supporting IPv6 filtering.</p><p>Note that Expander does not currently support IPv6 ranges. The Owned IPv6 Ranges page displays single owned IPv6 addresses.</p><p>See <a href="/pages/EBzK5QnogdGI00DBn4Ns">title\_title</a> for additional information.</p> | August 2023 |
| Splunk TA v5.0.0 Integration | The Cortex Xpanse Splunk integration allows you to forward Xpanse-discovered assets, services, and risks for management, visualization, correlation, and alerting within Splunk.

# Agent Instructions
This documentation is published with GitBook. GitBook is the documentation platform designed so that both humans and AI agents can read, navigate, and reason over technical content effectively. Learn more at gitbook.com.

## 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-expander-rn/features-introduced-before-2026/2023-releases/expander-release-22-minor-releases.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.
