All Implemented Interfaces:

Serializable
```
public class SshdSocketAddress
extends SocketAddress
```
A simple socket address holding the host name and port number. The reason it does not extend InetSocketAddress is twofold:
1. The InetSocketAddress performs a DNS resolution on the provided host name - which we don't want do use until we want to create a connection using this address (thus the toInetSocketAddress() call which executes this query
2. If empty host name is provided we replace it with the any address of 0.0.0.0
