# 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`, the Network Server will listen on all interfaces.

Ensure that you are running under a 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.
