## Quick detection methods

### By URL pattern

If you access InfluxDB via a URL, the hostname often indicates which product you're using:

| URL Pattern                                | Product                   |
| ------------------------------------------ | ------------------------- |
| `*.influxdb.io`                            | InfluxDB Cloud Dedicated  |
| `us-east-1-1.aws.cloud2.influxdata.com`    | InfluxDB Cloud Serverless |
| `eu-central-1-1.aws.cloud2.influxdata.com` | InfluxDB Cloud Serverless |
| `*.influxcloud.net`                        | InfluxDB Cloud 1 (legacy) |
| Other `*.cloud2.influxdata.com` regions    | InfluxDB Cloud (TSM)      |

### By default port

Different InfluxDB products use different default ports:

- **Port 8181**: InfluxDB 3 (Core or Enterprise)
- **Port 8086**: InfluxDB v1 or v2

### By HTTP headers

Check the `/ping` endpoint to examine HTTP response headers:

```bash
curl -i http://localhost:8086/ping
```

The response headers reveal your InfluxDB product:

| Headers                                                       | Product                |
| ------------------------------------------------------------- | ---------------------- |
| `x-influxdb-version: ^3.*`<br/>`x-influxdb-build: Core`       | InfluxDB 3 Core        |
| `x-influxdb-version: ^3.*`<br/>`x-influxdb-build: Enterprise` | InfluxDB 3 Enterprise  |
| `x-influxdb-version: ^2.*`<br/>`x-influxdb-build: OSS`        | InfluxDB OSS v2        |
| `x-influxdb-version: ^1.*`<br/>`x-influxdb-build: OSS`        | InfluxDB OSS v1        |
| `x-influxdb-build: Enterprise`<br/>(with v1 version)          | InfluxDB Enterprise v1 |

### InfluxDB 3 Core detection

Check the version using the `influxdb3` command:

```bash

### InfluxDB OSS v1 / Enterprise v1 detection

Check the version using `influxd`:

```bash

## Troubleshooting

### Can't access your InfluxDB instance?

If you can't directly access your InfluxDB instance:

1. Use the [interactive version detector](#identify-your-influxdb-version) above or {{< ask-ai-link link-text="Ask InfluxData AI" query="Help determine my InfluxDB version based on licensing, hosting, server age, and API." >}}
2. Answer questions about your setup:
   - License type (paid or free)
   - Hosting model (cloud or self-hosted)
   - Server age
   - Query language preferences
3. Get product recommendations based on your answers

### Still not sure?

If you're still uncertain, see the [Support and feedback](#bug-reports-and-feedback) options.
