# Datacenter proxies

> Connect to the datacenter network and configure location and session parameters.

Use a Datacenter proxy credential from your dashboard. Country, city, and session parameters use the same syntax as Residential proxies.

## Connection

| Protocol | Europe gateway | US gateway |
| - | - | - |
| HTTP | `proxy.doubledata.com:7777` | `us.proxy.doubledata.com:7777` |
| HTTPS | `proxy.doubledata.com:9999` | `us.proxy.doubledata.com:9999` |
| SOCKS5 | `proxy.doubledata.com:8888` | `us.proxy.doubledata.com:8888` |

The gateway selects where your application connects. The country parameter selects the exit country.

## Username parameters

| Parameter | Example | Behaviour |
| - | - | - |
| Country | `-country-de` | Request an exit in that country. |
| City | `-city-<city>` | Select a supported city from the dashboard generator. |
| Session | `-session-b2c3d4e5` | Reuse a sticky session. |
| Lifetime | `-ttl-30` | Request 1–120 minutes; requires a session ID. |

Keep the password, gateway, and targeting parameters unchanged during a session. Omit session and TTL for rotating connections.

> [!WARNING]
>
> This request uses your live proxy credentials and consumes traffic.

```bash theme={null}
curl --proxy https://proxy.doubledata.com:9999 \
  --proxy-user "${DOUBLEDATA_PROXY_USERNAME}-country-de-session-b2c3d4e5:${DOUBLEDATA_PROXY_PASSWORD}" \
  https://ipinfo.io/ip
```

Read usage through the shared [usage endpoint](https://doubledata.mintlify.site/api-reference/usage.md). Static Datacenter subscriptions are separate from these gateway credentials and are excluded from credential usage reports.
