NAT64 Well known prefix

Host behavior A host requiring information about presence of NAT64 and the IPv6 prefix used for protocol translation SHALL send a DNS query for AAAA records of a well-known IPv4-only fully qualified domain name: … ステートフルnat64は、ipv4ネットワークとipv6ネットワークを共存させるための技術であるnat64の方式の1つです。 nat64はipv6ネットワーク内の端末とipv4ネットワークの端末間の通信を可能にするためにipv6パケットをipv4パケットへ変換、またはその逆を行うものです。 NAT64 appends the hexadecimal equivalent of the IPv4 destination address to the IPv6 network prefix. well-known prefix: 64:ff9b::/96 eg: topo: PC1-> x0->DUT->X1->PC2. Understanding Persistent NAT and NAT64, Understanding Session Traversal Utilities for NAT (STUN) Protocol, Understanding NAT64 IPv6 Prefix to IPv4 Address-Persistent Translation, Persistent NAT and NAT64 Configuration Overview, Example: Configuring Address Persistent NAT64 Pools, Example: Supporting Network Configuration By Configuring … PC1是ipv6,PC2是IPV4(10.10.0.22 转成十六进制是AA 016). As the name implies, it keeps no state. The most commonly used type is definitely NAT44 but here we will focus on translating between IPv4 and IPv6.

This document reserves a "Well-Known Prefix" for use in an algorithmic mapping.

Private IPv4 addresses are dropped as specified in RFC 6052. 3 . This NAT64 uses the Well-Known Prefix 64:ff9b::/96 defined in to represent IPv4 addresses in the IPv6 address space and a single IPv4 address 203.0.113.1 assigned to its IPv4 interface.

Well-Known IPv4 Address: an IPv4 address that is well-known and mapped to the well-known name. well-known prefix: 64:ff9b::/96eg:topo: PC1-> x0->移动开发 NAT64: well-Known Prefix 原创 zy12805 最后发布于2017-03-01 15:39:10 阅读数 439 收藏 NAT64 and DNS64 in 30 seconds minutes

2. RFC 6052 IPv6 Addressing of IPv4/IPv6 Translators October 2010 2.IPv4-Embedded IPv6 Address Prefix and Format 2.1.Well-Known Prefix This document reserves a "Well-Known Prefix" for use in an algorithmic mapping. SRX Series,vSRX.

The stateless version maps the IPv4 address into an IPv6 prefix. NAT64 and DNS64 in 30 minutes 1. The routing is Bagnulo, et al. NAT64 – NAT from IPv6 to IPv4. This NAT64 uses the Well-Known Prefix 64:ff9b::/96 defined in [RFC6052] to represent IPv4 addresses in the IPv6 address space and a single IPv4 address 203.0.113.1 assigned to its IPv4 interface. ステートフルnat64. Cisco ASA 9.0 and later incorporates NAT64 but does not support the well-known prefix 64:ff9b::/96 and requires you to select your own prefix. I added the well-known-prefix to the list of allowed prefixes in ip64-addr.c. It does not implement DNS64 but provides inspection and NAT rewriting of DNS traffic passing through the NAT64 gateway. I added the well-known-prefix to the list of allowed prefixes in ip64-addr.c. 在DUT上设置了NAT64 policy,在PC1上访问PC2,比如ping可以加上PC2的ipv4的地址,比如:64 Private IPv4 addresses are dropped as specified in RFC 6052. There are two different forms of NAT64, stateless and statefull. See the sample NAT64 rule after this procedure for an example.
