Network base
============

**Energy.Base.Network** provides constants, delegates, and helper classes used by the higher-level networking classes in `Energy.Core`.

Constants
---------

| Constant | Description |
|----------|-------------|
| `DEFAULT_SOCKET_TIMEOUT` | Default socket timeout in milliseconds (10000). |
| `DEFAULT_SOCKET_BUFFER_SIZE` | Default buffer size (8192). |
| `DEFAULT_PING_TIMEOUT` | Default ping timeout (30000). |
| `DEFAULT_ADDRESS_FAMILY` | Default address family (`Unspecified`). |
| `IP4_PATTERN` | Regular expression for IPv4 addresses. |
| `IP6_PATTERN` | Regular expression for IPv6 addresses. |

Delegates
---------

The class defines delegates for network events:

- `ConnectDelegate`
- `CloseDelegate`
- `ListenDelegate`
- `AcceptDelegate`
- `SendDelegate<T>` and `SendDelegate`
- `ReceiveDelegate<T>` and `ReceiveDelegate`
- `ErrorDelegate`
- `ExceptionDelegate`

Settings
--------

**Energy.Base.Network.Settings** holds basic network configuration.

```csharp
Energy.Base.Network.Settings settings = new Energy.Base.Network.Settings
{
    SocketTimeout = 5000,
    SocketBufferSize = 4096,
    AddressFamily = System.Net.Sockets.AddressFamily.InterNetwork,
};
```

Connection
----------

**Energy.Base.Network.Connection** holds connection information.

```csharp
Energy.Base.Network.Connection connection = new Energy.Base.Network.Connection
{
    Host = "127.0.0.1",
    Port = 8080,
    Protocol = "tcp",
    Type = System.Net.Sockets.ProtocolType.Tcp,
};
```

Validation
----------

```csharp
bool valid = Energy.Base.Network.IsValidAddress("192.168.1.1");
bool valid6 = Energy.Base.Network.IsValidAddress("::1");
```
