NAT hairpinning, also known as NAT loopback or NAT reflection, [26] is a feature in many consumer routers [27] where a machine on the LAN is able to access another machine on the LAN via the external IP address of the LAN/router (with port forwarding set up on the router to direct requests to the appropriate machine on the LAN).
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 ...
Port forwarding via NAT router. In computer networking, port forwarding or port mapping is an application of network address translation (NAT) that redirects a communication request from one address and port number combination to another while the packets are traversing a network gateway, such as a router or firewall.
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 ...
the "secure NAT" subsection of the SNAT section states the obvious interpretation of the term "secure nat" but doesn't say what is actually meant when a vendor says a "NAT" is secure Add NAT behavior section (see Talk:Network address translation#NAT behavior article needed )
STUN (Session Traversal Utilities for NAT; originally Simple Traversal of User Datagram Protocol (UDP) through Network Address Translators) is a standardized set of methods, including a network protocol, for traversal of network address translator (NAT) gateways in applications of real-time voice, video, messaging, and other interactive communications.
A computer network diagram is a schematic depicting the nodes and connections amongst nodes in a computer network or, more generally, any telecommunications network. Computer network diagrams form an important part of network documentation.
The overarching definitions of the two principal name spaces on the Internet, the Internet Protocol address (IP address) space and the Domain Name System (DNS), are directed by a maintainer organization, the Internet Corporation for Assigned Names and Numbers (ICANN).
