UPnP (Universal Plug and Play) supports
null-setting for networking, can
automatically find a variety of networked
devices. When UPnP is enabled, UPnP-
enabled devices are allowed to
dynamically access the network, obtain
IP addresses, and transmit performance
information. If you have DHCP and
DNS servers on your network, you can
automatically obtain DHCP and DNS
services. UPnP-enabled devices can be
automatically disconnected from the
network without affecting the device or
other devices on the network.
