# Ping

> Ping any given IP address (given in dot notation).

## Definition

* **Type:** Class
* **Namespace:** [UnityEngine](/engine/6000.0/script-reference/unityengine.md)
* **Assembly:** UnityEngine.CoreModule

```csharp
public sealed class Ping
```

## Remarks

The ping operation is asynchronous and a ping object can be polled for status using [Ping.isDone](/engine/6000.0/script-reference/unityengine/ping/isdone.md). When a response is received it is in [Ping.time](/engine/6000.0/script-reference/unityengine/ping/time.md).

**Windows Store Apps**: A stream socket is used to mimic ping functionality, it will try to open a connection to specified IP address using port 80. For this to work correctly, InternetClient capability must be enabled in Package.appxmanifest.

**Android**: ICMP sockets are used for ping operation if they're available, otherwise Unity spawns a child process **/system/bin/ping** for ping operations. To check if ICMP sockets are available, you need to read the contents for **/proc/sys/net/ipv4/ping*****group*****range**. If ICMP sockets are available, this file should contain an entry for **0 2147483647**.
