# connectionOnDemand

The specified node name or address can be reached using the current network configuration, but a connection must first be established.

## Declaration

```swift
static var connectionOnDemand: SCNetworkReachabilityFlags { get }
```

## Discussion

Discussion The connection will be established “On Demand” by the CFSocketStream programming interface (see CFStream Socket Additions for information on this). Other functions will not establish the connection.
