```
public InetSocketAddress getReachableAddress()
                                      throws NoRouteToHostException
```
    Returns a reachable address. If none is reachable than throws exception. The function is nondeterministic in the sense that the result of calling this function twice with the same set of reachable addresses might lead to different results.
    
    Returns:
    
    address which is reachable.
    
    Throws:
    
    NoRouteToHostException - if none of the addresses are reachable
  - getAllReachableAddresses
```
public Set<InetSocketAddress> getAllReachableAddresses()
```
    Returns a set of all reachable addresses. If none is reachable than returns empty set.
    
    Returns:
    
    all addresses which are reachable.
  - getAllReachableAddressesOrAll
```
public Set<InetSocketAddress> getAllReachableAddressesOrAll()
```
    Returns a set of all reachable addresses. If none is reachable than returns all addresses.
    
    Returns:
    
    all reachable addresses, or all addresses if none is reachable.
  - getReachableOrOne
```
public InetSocketAddress getReachableOrOne()
```
    Returns a reachable address or an arbitrary one, if none is reachable. It throws an exception if there are no addresses registered. The function is nondeterministic in the sense that the result of calling this function twice with the same set of reachable addresses might lead to different results.
    
    Returns:
    
    address which is reachable or fist one.
    
    Throws:
    
    NoSuchElementException - if there is no address registered
  - recreateSocketAddresses
```
public void recreateSocketAddresses()
```
    Performs a parallel DNS lookup for all addresses. If the DNS lookup fails, then address remain unmodified.
  - getOne
```
public InetSocketAddress getOne()
```
    Returns an address from the set.
    
    Returns:
    
    address from a set.
    
    Throws:
    
    NoSuchElementException - if there is no address registered
  - size
```
public int size()
```
    Returns the number of addresses in the set.
    
    Returns:
    
    the number of addresses.
