All Methods Instance Methods Concrete Methods
Modifier and Type	Method	Description

`boolean`	`rescan()`	Call when IP or network connectivity might have changed.
`void`	`start()`	Blocking, may take a while.
`void`	`stop()`	Blocking, may take a while, up to 20 seconds

  - rescan
```
public boolean rescan()
```
    Call when IP or network connectivity might have changed. Starts UPnP if previous start failed, else starts a search. Must have called start() first, and not called stop(). Should be fast. This only starts the search, the responses will come in over the MX time (3 seconds).
    
    Returns:
    
    true if a rescan was actually fired off
