Guidelines for Using IPv6 Transition Mechanisms during IPv6 Deployment
Abstract
The Internet continues to grow beyond the capabilities of IPv4. An
expansion in the address space is clearly required. With its
increase in the number of available prefixes and addresses in a
subnet, and improvements in address management, IPv6 is the only real
option on the table. Yet, IPv6 deployment requires some effort,
resources, and expertise. The availability of many different
deployment models is one reason why expertise is required. This
document discusses the IPv6 deployment models and migration tools,
and it recommends ones that have been found to work well in
operational networks in many common situations.

RFC 6180 IPv6 Transition Guidelines May 2011
1. Introduction
The Internet continues to grow beyond the capabilities of IPv4. The
tremendous success of the Internet has strained the IPv4 address
space, which is no longer sufficient to fuel future growth. At the
time of this writing, August 2010, the IANA "free pool" contains only
14 unallocated unicast IPv4 /8 prefixes. Credible estimates based on
past behavior suggest that the Regional Internet Registries (RIRs)
will exhaust their remaining address space by early 2012, apart from
the development of a market in IPv4 address space. An expansion in
the address space is clearly required. With its increase in the
number of available prefixes and addresses in a subnet, and
improvements in address management, IPv6 is the only real option on
the table.
John Curran, in "An Internet Transition Plan" [RFC5211], gives
estimated dates for significant points in the transition; while the
