Technical Summary This document provides advice to network operators about deployment of the 6to4 technique for automatic tunneling of IPv6 over IPv4. It is principally addressed to Internet Service Providers, including those that do not yet support IPv6, and to Content Providers. Some advice to implementers is also included. The intention of the advice is to minimise both user dissatisfaction and help desk calls. Working Group Summary The IPv6 Operations Working Group discussed this in the first half of 2011. There is general consensus that the guidelines for improving 6to4 behavior are reasonable and helpful. Document Quality The document was written by the original author of 6to4. Many of the people that commented in support of it observed that it was well written and informative. There are numerous 6to4 implementations; the issue in this context is that 6to4 was intended to have operational support when designed, and has been implemented largely without that operational support. As a result, it often doesn't perform as intended. This was discussed in Geoff Huston's talk in v6ops at IETF-80. Personnel Fred Baker is shepherd.
