# derby.drda.host property

Causes the Network Server to listen on a specific network interface. This property allows multiple instances of Network Server to run on a single machine, each using its own unique host:port combination. The host needs to be set to enable remote connections. By default, the Network Server will listen only on the loopback address. If the property is set to 0.0.0.0, Network Server will listen on all interfaces. Ensure that you are running under the security manager and that user authorization is enabled before you enable remote connections with this property.

#### Syntax

    derby.drda.host=hostname

#### Default

If no host name is specified, the Network Server listens on the loopback address of the current machine (localhost).

#### Example

    derby.drda.host=myhost

#### Static or dynamic

Static. You must restart the Network Server for changes to take effect.
