## Dns::BeginGetHostEntry(String, AsyncCallback, System::SharedPtr\<Object\>) method


Initiates an asynchronous operation to create a new IPHostEntry-class instance using the specified string that contains a host name or IP address.

```cpp
static System::SharedPtr<IAsyncResult> System::Net::Dns::BeginGetHostEntry(String hostNameOrAddress, AsyncCallback requestCallback, System::SharedPtr<Object> stateObject)
```


| Parameter | Type | Description |
| --- | --- | --- |
| hostNameOrAddress | String | The string that contains a hostname or IP address. |
| requestCallback | AsyncCallback | A callback to be called when the operation completes. |
| stateObject | System::SharedPtr\<Object\> | User-provided data used to uniquely identify each asynchronous operation. |

### ReturnValue

An [IAsyncResult](../../../system/iasyncresult/) object representing the initiated asynchronous operation.
