UPnP logo as promoted by the UPnP Forum (2001–2016) and Open Connectivity Foundation (2016–present). Universal Plug and Play (UPnP) is a set of networking protocols on the Internet Protocol (IP) that permits networked devices, such as personal computers, printers, Internet gateways, Wi-Fi access points and mobile devices, to seamlessly discover each other's presence on the network and ...
Diagram of the UPnP ' s discovery phase. Internet Gateway Device (UPnP IGD) Control Protocol is a protocol based on UPnP for mapping ports in network address translation (NAT) setups, supported by some NAT-enabled routers.
A UPnP client, also called a control point, functions as a digital audio/video remote control. Control points automatically detect UPnP servers on the network to browse content directories and request the transfer or streaming of media. A UPnP media renderer performs the actual audio or video rendering.
Carrier-grade NAT. Carrier-grade NAT (CGN or CGNAT), also known as large-scale NAT (LSN), is a type of network address translation (NAT) used by ISPs in IPv4 network design. With CGNAT, end sites, in particular residential networks, are configured with private network addresses that are translated to public IPv4 addresses by middlebox network address translator devices embedded in the network ...
[2] [3] Many routers and network attached storage (NAS) devices have built-in DLNA support, as well as software applications like Windows Media Player. [ 4 ] [ 5 ] DLNA was created by Sony and Intel and the consortium soon included various PC and consumer electronics companies, publishing its first set of guidelines in June 2004. [ 6 ]
Multiple registrars should have the ability to connect to the AP. UPnP is intended to apply only to a wired medium, while actually it applies to any interface to which an IP connection can be set up. Thus, having manually set up a wireless connection, the UPnP can be used over it in the same manner as with the wired connection.

Various NAT traversal techniques have been developed: NAT Port Mapping Protocol (NAT-PMP) is a protocol introduced by Apple as an alternative to IGDP. Port Control Protocol (PCP) is a successor of NAT-PMP. UPnP Internet Gateway Device Protocol (UPnP IGD) is supported by many small NAT gateways in home or small office settings. It allows a ...
