UPnP Operations

Addressing:
UPnPv1 devices MAY support IPv4, IPv6, or both. For IPv4, each device should be set to work
as a DHCP client. When the device is connected to the network, it is able to connect to and obtain IP
settings from a DHCP server. If the DHCP server is not found, the device assigns itself an IP address
(169.254.0.0/16) using the auto-IP mechanism.

Discovery: Whenever a device is added to the network, it will advertise its service to other devices on
the network. A control point can also discover services provided by the devices.

Description: Control points can get detailed service information from the devices' description in XML
format. The description may include product name, model name, serial number, vendor ID, and
embedded services, etc.

Control: Devices can be manipulated by control points through Control message.

Eventing: Devices can send event messages to notify control points if there is any update on the services
provided.

Presentation: Each device can provide its own control interface in the form of a URL link. This allows
users to access the web management interface on the device by entering the URL address and control
the device.
