# Datacenter Proxies

Datacenter proxies use IP addresses assigned from datacenter servers to route your traffic and access locations around the world. With a shorter journey and simplified architecture, datacenter proxies are both the fastest and most cost-effective proxy option.

## IP Rotation Behavior

Datacenter proxies provide a **static exit IP** — the same IP address is used for all connections throughout the lifetime of the proxy. Every tab, request, and reconnection within a browser session exits through the same IP.

## Configuration

Datacenter proxies require a country to route traffic through:

<CodeGroup>
  ```typescript Typescript/Javascript theme={null}
  import Kernel from '@onkernel/sdk';

  const kernel = new Kernel();

  const proxy = await kernel.proxies.create({
    type: 'datacenter',
    name: 'my-us-datacenter',
    config: {
      country: 'US',
    },
  });

  const browser = await kernel.browsers.create({
    proxy_id: proxy.id,
  });
  ```

  ```python Python theme={null}
  from kernel import Kernel

  kernel = Kernel()

  proxy = kernel.proxies.create(
      type="datacenter",
      name="my-us-datacenter",
      config={
          "country": "US",
      }
  )

  browser = kernel.browsers.create(proxy_id=proxy.id)
  ```
</CodeGroup>

## Configuration Parameters

* **`country`** (optional) - ISO 3166 country code (e.g., `US`, `GB`, `FR`) or `EU` for European Union exit nodes
* **`bypass_hosts`** (optional) - Array of hostnames that bypass the proxy and connect directly (max 100 entries)

## Bypass hosts

Configure specific hostnames to bypass the proxy:

<CodeGroup>
  ```typescript Typescript/Javascript theme={null}
  import Kernel from '@onkernel/sdk';

  const kernel = new Kernel();

  const proxy = await kernel.proxies.create({
    type: 'datacenter',
    name: 'datacenter-with-bypass',
    config: {
      country: 'US',
    },
    bypass_hosts: [
      'localhost',
      'internal.service.local',
      '*.amazonaws.com',
    ],
  });
  ```

  ```python Python theme={null}
  from kernel import Kernel

  kernel = Kernel()

  proxy = kernel.proxies.create(
      type="datacenter",
      name="datacenter-with-bypass",
      config={
          "country": "US",
      },
      bypass_hosts=[
          "localhost",
          "internal.service.local",
          "*.amazonaws.com",
      ]
  )
  ```
</CodeGroup>

Bypass hosts support exact hostnames and wildcard subdomains (`*.example.com`). See the [overview](/proxies/overview#bypass-hosts) for full details.
