Cortex XSOAR accesses new versions from and uploads licenses to this repository.

| 443 | Outbound | | Download packages required for installation | | 80 | Outbound | **Cortex XSOAR DNS records** You need to add the following DNS records to your DNS server to resolve hostnames to the cluster IP address (only static, DHCP is not supported). These DNS records (for a given tenant) should all point to the same cluster IP address to ensure a single entry point. For MSSP, each tenant must have its own set of **`xsoar.*`**, **`api-*`**, and **`ext-*`** FQDNs pointing to the tenant cluster's single entry point. {% hint style="info" %} ### Note Verify the internal DNS correctly resolves these addresses. DNS resolution failure for these FQDNs can cause communication issues, such as with MSSP sync when a proxy is used, or even when bypassing the proxy with **No Proxy**. {% endhint %} * **`xsoar..`**: The Cortex XSOAR DNS name for accessing the UI. For example, **`xsoar.mycompany.com`**. * **`api-.`**: The Cortex XSOAR DNS name that is mapped for API access. For example, **`api-xsoar.mycompany.com`**. This should be a CNAME entry pointing to the same cluster IP address. * **`ext-.`**: The Cortex XSOAR DNS name that is mapped to access long running integrations. For example, **`ext-xsoar.mycompany.com`**. This should be a CNAME entry pointing to the same cluster IP address. --- # 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-xsoar-8-on-prem/8.10/onboard-cortex-xsoar/cortex-xsoar-installation/system-requirements/url-requirements.md?ask=&goal= ``` `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.
