The packet is then forwarded to the external network. The NAT device then makes an entry in a translation table containing the internal IP address, original source port, and the translated source port. Subsequent packets from the same internal source IP address and port number are translated to the same external source IP address and port number.
In computer networking, source routing, also called path addressing, allows a sender of a data packet to partially or completely specify the route the packet takes through the network. [1] In contrast, in conventional routing , routers in the network determine the path incrementally based on the packet's destination.
Each language is assigned a two-letter (set 1) and three-letter lowercase abbreviation (sets 2–5). [2] Part 1 of the standard, ISO 639-1 defines the two-letter codes, and Part 3 (2007), ISO 639-3 , defines the three-letter codes, aiming to cover all known natural languages , largely superseding the ISO 639-2 three-letter code standard.
Loose Source Routing is an IP option which can be used for address translation. LSR is also used to implement mobility in IP networks. [3] Loose source routing uses a source routing option in IP to record the set of routers a packet must visit. The destination of the packet is replaced with the next router the packet must visit.
Address translation defined in RFC 6052 [4] is a stateless mapping scheme, which embeds IPv4 address in network specific IPv6 prefix and forms IPv4-converted and IPv4-translatable addresses. The IPv4-converted IPv6 addresses are the IPv6 addresses used to represent IPv4 nodes in an IPv6 network.
IP addressing entails the assignment of IP addresses and associated parameters to host interfaces. The address space is divided into subnets , involving the designation of network prefixes. IP routing is performed by all hosts, as well as routers , whose main function is to transport packets across network boundaries.
IP forwarding algorithms in most routing software determine a route through a shortest path algorithm. In routers, packets arriving at an interface are examined for source and destination addressing and queued to the appropriate outgoing interface according to their destination address and a set of rules and performance metrics.
A virtual IP address (VIP or VIPA) is an IP address that does not correspond to a physical network interface. Uses for VIPs include network address translation (especially, one-to-many NAT ), fault-tolerance, and mobility .
