NetworkAddress (OSGi Residential Release 6)

```
public interface NetworkAddress
```
This interface represents an IP address information.
NetworkAddress interface provides information of IP addresses available in which execution environment on a Network Interface Information Service bundle is running. IP address information service is set the following information as service property.
- NETWORKADAPTER_TYPE : Network Interface Type
- IPADDRESS_VERSION : IP Address Version
- IPADDRESS_SCOPE : IP Address Scope
- IPADDRESS : IP Address
- SUBNETMASK_LENGTH : Subnet Mask Length(IPv4) or Prefix Length(IPv6)
- NETWORKADAPTER_PID : Service PID of the NetworkAdapter service to which this service belongs
NetworkAddress service is registered with the service registry for each available IP address. When associated IP addresses are deleted, or the network interface to which the IP address is bound becomes unavailable, the NetworkAddress service is unregistered. When the associated IP address changes, NetworkAddress service is updated. The user bundle can detect the change of IP address by monitoring the registration or unregistering, updating of NetworkAddress service. Because IP addresses are bound to the network interface, if any, Service PID of the associated NetworkAdapter service and its network interface type are set to service property. NetworkAdapter service MUST be registered after the all associated NetworkAddress services are registered. On the other hand, when unregistering services, after associated NetworkAdapter service is unregistered, NetworkAddress of all related services are unregistered.
