Stateless Address Translation Considerations

PROS

• implicit address binding and unbinding

  • scalable and resilient to failure

• using IPv4 compatible/mapped IPv6 addresses

  • no need to update checksum values of UDP/TCP/ICMP
  • no need to update IP addresses in application data stream

CONS

• IPv6 hosts must have a routable IPv4 address

• IPv6 routers must support routes to IPv4-compatible-IPv6 and IPv4-mapped-IPv6 addresses
