Gets or sets the local hostname this transport protocol will use when listening
for incoming traffic from the ZIS. Sets the local host name or IP address this transport
protocol will use
when establishing a local socket. By default, localhost is assumed.
This property is useful when more than one network interface is available
on the machine, or when the agent wishes to exercise more control over
the exact hostname or IP address that is registered with the ZIS (e.g.
"localhost" versus "127.0.0.1" versus the IP address or DNS host name of
the local machine.)
The host name or IP address passed to the setHost method.
Defaults to "localhost"
