IPv6 More Efficient than IPv4

  • Avoids the need for network address translation (NAT)
  • Provides faster routing through the network by using simplified headers
  • Prevents network fragmentation
  • Avoids broadcasting for neighbor address resolution

DNS64/NAT64 Transitional Workflow

为了缓解IPv4的用完问题，NAT被实现来解决IPv的问题。NAT（Network Address Translation，网络地址转换）是将IP数据报文头中的IP地址转换为另一个IP地址的过程。在实际应用中，NAT主要用于实现私有网络访问公共网络的功能。这种通过使用少量的公网IP地址代表较多的私网IP地址的方式，将有助于减缓可用IP地址空间的枯竭。
