# Residential Proxies - ASN Targeting

Residential proxies support operating system Autonomous System Number (ASN) targeting, allowing you to request proxy exits associated with a specific Autonomous System Number (ASN).

## How to Target an ASN

To target a specific network provider, add the `-asn-` parameter to your proxy username, followed by the ASN.

| ASN                                              | Parameter   | Example         |
| ------------------------------------------------ | ----------- | --------------- |
| COMCAST-7922 (Comcast Cable Communications, LLC) | `-asn-7922` | `user-asn-7922` |
| GEOPLEX (AT\&T)                                  | `-asn-7948` | `user-asn-7948` |

For example, to request a Comcast exit:

```text Username theme={null}
user-asn-7922
```

### Combining ASN Targeting with Other Parameters

ASN targeting can be combined with other Regular Residential parameters, including country targeting and sticky sessions.

| Example                                                   | Result                                                                 |
| --------------------------------------------------------- | ---------------------------------------------------------------------- |
| `user-country-us-asn-7922`                                | COMCAST-7922 exit in the United States                                 |
| `user-country-us-asn-7922-session-1235469420-lifetime-15` | COMCAST-7922 exit in the United States with a 15-minute sticky session |

<Note>
  Replace `user` with your own proxy username in all examples.
