### Dynamic IP Address Retrieval

For the most up-to-date list of Uptime Monitoring IP addresses, you can query the following API endpoint:

```plaintext
https://us.sentry.io/api/0/uptime-ips/
```

This endpoint returns a newline-separated list of all current Uptime Monitoring IP addresses (for all regions) that can be programmatically processed in your allowlist configurations.

<Alert title="Note" level="warning">

Uptime Monitoring IP addresses may change over time. If you need to programmatically verify whether a visitor is a Sentry bot, we recommend checking the [user agent](/product/alerts/uptime-monitoring/troubleshooting/#user-agent) instead.

</Alert>

### Information for Hosting Providers

If you're a hosting provider (like Vercel, Netlify, or similar platforms), please consider the following guidance regarding Sentry's Uptime Monitoring:

Many organizations use Sentry to monitor the uptime of their websites and applications. When Sentry's monitoring IPs are blocked, it creates false outage alerts for all customers trying to monitor sites on your platform.

We probably don't want to recommend looking at the user agent -- since this can be spoofed

3. Ensure rate limiting policies do not inadvertently block Sentry's monitoring capabilities
4. Consider implementing automatic updates of allowlisted IPs using our API endpoint

By ensuring Sentry can properly monitor sites on your platform, you'll improve the reliability monitoring experience for all your customers who use Sentry.
