Network address translation between a private network and the Internet. Network address translation (NAT) is a method cane IP header of packets while they are in transit across a traffic routing device. [ 1 ] The technique was originally used to bypass the need to assign a new address to every host when a network was moved, or when the upstream ...
Packet Tracer is commonly used by NetAcad students, since it is available to download after creating a free account. [9] However, due to functional limitations, it is intended by Cisco to be used only as a learning aid, not a replacement for Cisco routers and switches . [ 8 ]
NAT traversal. Network address translation traversal is a computer networking technique of establishing and maintaining Internet Protocol connections across gateways that implement network address translation (NAT). NAT traversal techniques are required for many network applications, such as peer-to-peer file sharing and voice over IP. [1]
NAT64 is an IPv6 transition mechanism that facilitates communication between IPv6 and IPv4 hosts by using a form of network address translation (NAT). The NAT64 gateway is a translator between IPv4 and IPv6 protocols, [1] for which function it needs at least one IPv4 address and an IPv6 network segment comprising a 32-bit address space.
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 ...
v. t. e. Port Control Protocol (PCP) is a computer networking protocol that allows hosts on IPv4 or IPv6 networks to control how the incoming IPv4 or IPv6 packets are translated and forwarded by an upstream router that performs network address translation (NAT) or packet filtering. By allowing hosts to create explicit port forwarding rules ...
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 ...
Dynamic routing, also called adaptive routing, [1][2] is a process where a router can forward data via a different route for a given destination based on the current conditions of the communication circuits within a system. [3] The term is most commonly associated with data networking to describe the capability of a network to 'route around ...
