# Global Lookup

Query and enrich global internet scan data for IP addresses, domains, and certificate hashes in Cortex XSIAM.

Global Lookup allows you to query global internet scan data for certificate hashes, IP addresses, and domains. This internet data is enriched with registration information, geolocation, related certificates, observed services, ASNs, and passive DNS records. Global Lookup is not limited to your own attack surface, offering clear insights into indicator ownership and accelerating the analysis of potentially malicious indicators.

Global Lookup enables you to:

* View and analyze up to 30 days of data, and select up to a 30-day range to search within the last 6 months.
* View the services that have been open on a given IP address over the last 6 months.
* Pivot to Global Lookup directly from IP addresses, domains, and certificates found in attack surface or vulnerability issues.

How to use Global Lookup

1. Navigate to **Modules** → **Attack Surface** → **Global Lookup**.
2. Enter an IP address, domain, or certificate hash (MD5, SHA1, and SHA256) in the Search box.

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 by asking a question.

Perform an HTTP GET request on the following URL with the `ask` and `goal` query parameters:

```
GET https://cortex-docs.paloaltonetworks.com/cortex-xsiam/detect-investigate-and-respond-to-threats/attack-surface-management/global-lookup.md?ask=<question>&goal=<user_goal>
```

`ask` is the immediate question: it should be specific, self-contained, and written in natural language.
`goal` is what the user is ultimately trying to achieve, the reason they need the answer. Sharing it helps GitBook give you a better, more relevant answer. A goal is most helpful when it describes the outcome the user wants rather than restating the question. For example, with `ask=how do I create an API token`, a goal like `automate deployments from our CI pipeline` lets GitBook tailor the answer to that use case.

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.
