# serverAddress

The address of the VPN server.

## Declaration

```swift
var serverAddress: String? { get set }
```

## Discussion

Discussion The format of the value of this property depends on the type of VPN protocol in use. For example, for IPSec the value should be a hostname or an IP address. For a custom SSL-VPN protocol the value may be a URL. The only requirement imposed by the Network Extension framework is that this property must have a non-nil string value for the protocol configuration to be valid.
