Translation

• may prefer to use IPv6-IPv4 protocol translation for:

  • new kinds of Internet devices (e.g., cell phones, cars, appliances)
  • benefits of shedding IPv4 stack (e.g., serverless autoconfig)

• this is a simple extension to NAT techniques, to translate header format as well as addresses

  • IPv6 nodes behind a translator get full IPv6 functionality when talking to other IPv6 nodes located anywhere
  • they get the normal (i.e., degraded) NAT functionality when talking to IPv4 devices
  • methods used to improve NAT functionality (e.g, RSIP) can be used equally to improve IPv6-IPv4 functionality
