Network address translation between a private network and the Internet. Network address translation (NAT) is a method of mapping an IP address space into another by modifying network address information in the IP header of packets while they are in transit across a traffic routing device. [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.
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]
6rd was developed by Rémi Després.It is a mechanism to facilitate rapid deployment of the IPv6 service across IPv4 infrastructures of Internet service providers ().It uses stateless address mappings between IPv4 and IPv6 addresses, and transmits IPv6 packets across automatic tunnels that follow the same optimized routes between customer nodes as IPv4 packets.
Shared address space [4] for communications between a service provider and its subscribers when using a carrier-grade NAT 127.0.0.0/8 127.0.0.0–127.255.255.255
It has fewer architectural problems than traditional IPv4 NAT; for example, it is stateless and preserves the reachability attributed to the end-to-end principle. However, the method may not translate embedded IPv6 addresses properly (IPsec can be impacted), and split-horizon DNS may be required for use in a business environment.
To send an IPv6 packet over an IPv4 network to a 6to4 destination address, an IPv4 header with protocol type 41 is prepended to the IPv6 packet. The IPv4 destination address for the prepended packet header is derived from the IPv6 destination address of the inner packet (which is in the format of a 6to4 address), by extracting the 32 bits ...
IVI Translation refers to a stateless IPv4/IPv6 translation technique. [1] It allows hosts in different address families (IPv4 and IPv6) communicate with each other and keeps the end-to-end address transparency. [2] Stateless NAT64 can be used in 4 different scenarios: [3] An IPv6 network to the IPv4 Internet; The IPv4 Internet to an IPv6 network
